Abstract: At home and abroad in recent years, the medical profession to captopril and hydrogen chloride thiazole and indapamide fall blood pressure of old medicine compound preparation for treating primary hypertension achieve good effect, the new usage will greatly expand the amount of captopril. Because captopril has wide clinical application and the characteristics of huge economic benefits, in addition to the various types of high blood pressure have obvious antihypertensive effect, but also has high curative effect, side effect is small, possesses the advantages of less dosage, the study of its synthetic methods has caused the attention of scholars, the synthetic route design, studied the process conditions. A novel protocol for the Michael addition of  thiolacetic acid to methacrylic acid vinyl ester was developed using a basic ionic liquid[bmim]OH as catalyst and solvent,the reaction was carried out at room temperature and could obtain good yields in 30 min. A new synthesis of active pharmaceutical ingredients named captopril,the was achieved by Michael addition and N-acylation,in high purity from methacrylic acid vinyl ester.

KeyWords: captopril, craft process, synthetic rout
