The structure and synthesis of TPC is outlined in Scheme 1. Briefly‚ the compound 1 was synthesized as per literature procedure. 2 was synthesized by reacting 1-methy pyrazole-4-boronic pinacol ester with 1 by suzuki-coupling‚ the final product TPC was synthesized by treating with malononitrile in the presence of piperidine as a base and ethanol as solvent. The detailed synthesis procedure given in the experimental section. The structure and purity of TPC was unambiguously confirmed by 1H and 13C
