Hazard Information | Back Directory | [Uses]
N-[4-Cyano-3-(trifluoromethyl)phenyl]-2-methyl-2-oxiranecarboxamide, is an intermediate in synthesis of more complex pharmaceutical compounds. It is used in the synthesis of potential impurities of Bicalutamide (B382000), which is an oral nonsteroidal, anti-androgen drug used for prostate cancer. | [Synthesis]
General procedure for the synthesis of N-[4-cyano-3-(trifluoromethyl)phenyl]methoxyacrylamide from N-(4-cyano-3-(trifluoromethyl)phenyl)methoxyacrylamide: N-[4-cyano-3-(trifluoromethyl)phenyl]-2-methacrylamide (50.8 g, 0.2 mol) and phthalic anhydride (47.3 g, 0.32 mol) were dissolved in 350 ml of 1,2-dichloroethane. 50% hydrogen peroxide (23.1 g, 0.34 mol) was added slowly and dropwise at 35?40 °C. The progress of the reaction was monitored by HPLC until the content of the feedstock N-[4-cyano-3-(trifluoromethyl)phenyl]-2-methylacrylamide decreased to less than 0.5% and the reaction was completed. Subsequently, 1,2-dichloroethane was removed by distillation to give the crude product. To the crude product, 300 g of water was added and neutralized by adding 26 g of sodium carbonate. Next, 13 g of sodium sulfate was added and filtered after stirring for 0.5 hours. The filter cake was washed with 50 g of water and dried to give the final product N-[4-cyano-3-(trifluoromethyl)phenyl]-2,3-epoxy-2-methylpropanamide 49 g in 90.7% yield. | [References]
