Purpose Acetophenetidin can be formed through two methods‚ Williamson ether synthesis and amide synthesis. By working in groups of two we were able to complete both methods of synthesis routes. The end result should be the synthesis of a similar product‚ by verification between the two individuals. Reaction Experiment and Observations Amide Synthesis of Acetophenetidin The Synthesis reaction began by removing the colored impurities from the p-phenetidine‚ accomplished by mixing

What is the theoretical yield of amide 1 in figure 3? The amine is the limiting reagent. The theoretical yield is 4.81 grams of amide 1. 2. What is the theoretical yield of Lidocaine? Base calculations on 2‚6-dimethylaniline. The theoretical yield of lidocaine is 5.71 grams. 3. How many molar equivalents of diethyl amine are used in

Starting material may be any lysergic acid derivative‚ from ergot on rye grain or from culture‚ or morning glory seeds or from synthetic sources. Preparation #1 uses any amide‚ or lysergic acid as starting material. Preparations #2 and #3 must start with lysergic acid only‚ prepared from the amides as follows: 10 g of any lysergic acid amide from various natural sources dissolved in 200 ml of methanoic KOH solution and the methanol removed immediately in vacuo. The residue is treated with 200 ml of an 8%

In the same year Pradidphol synthesized novel naphthoquinone aromatic amides and evaluated for anticancer activity. Benzamide 80 showed potent inhibition against NCI-H187 cell lines while naphthamides 81 and 83 were the most potent inhibition against KB cells. The decatenation assay revealed that compounds 82 and 83 inhibit

Objectives This experiment aims to analyse the given sample of acetaminophen‚ Sample A‚ to see if it complies with the monograph in the British Pharmacopoeia (BP) for the identification of acetaminophen‚ the limit test for p-aminophenol and the assay for acetaminophen. Procedure Identification for Acetaminophen Potassium bromide (KBr) disc technique was used to prepare the sample for the infrared absorption spectrophotometry. The agate mortar and pestle were cleaned with absolute ethanol using

groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine. Aside from Caffeine‚ Acetaminophen has one amide functional group. This makes it the second most polar analgesic. In addition‚ Acetylsalicylic Acid has an ester group. Since ester group is not as polar as either amine or amide groups‚

Acetaminophen. The peaks that were at the highest wavenumbers were analyzed first. The strong peak at 3325.82 cm-1 was an indicator that there was stretching occurring between a Hydrogen and Nitrogen atom. This signified that Acetaminophen could contain an amide group. The next defined peak is located at 3162.26 cm-1‚ and the section between these two peaks has a slight broad descend. This broad curve is tagged as stretching between a Hydrogen and Oxygen bond. Since the N-H bond deleted a broad curve typically

The net dipole moment of the molecule Atenolol has amide functional group that makes it the most polar out of three drugs. Because of the greater electronegativity of oxygen‚ the carbonyl (C=O) is a stronger dipole than the N–C dipole. The presence of a C=O dipole and‚ to a lesser extent N–C dipole‚ allows amides to act as H-bond acceptors. The presence of N–H dipoles allows amides to function as H-bond donors as well. Therefore‚ atenolol is the most polar drug and

The early twentieth century led to the discovery of penicillin‚ which revolutionized the use of curative agents to combat many bacterial contagions found around the globe. This was particularly useful in 1943 when the War Production Board outlined a plan to mass-produce a powdered formula of the drug to aid in the WWII American war effort.1 Penicillin’s use on Allied forces in the field reduced the number of amputations and deaths by an estimated 12-15%.2 Despite penicillin’s continued use today
