OBJECTIVE:A facile synthesis of sodium salt of 5-chloro-3-(2-thenoyl)-2-oxindole-1-carboxyamide from common 4-chloroaniline is described.METHODS:The key intermediate 5-chloro-2-oxindole(4) is prepared successfully in 75% yield from 4-chloroaniline in four steps, and converted by reaction with trichloroacetyl isocyanate into the N-trichloroacetyl-5-chloro-2-oxindole-1-carboxyamide,and followed hydrolysis, then 5-chloro-2-oxindole-1-carboxyamide(5) is obtained. Condensation of (5) with 2-thenoyl chloride gives 5-chloro-3-(2-thenoyl)- 2-oxindole-carboxyamide(6). The title compound is obtained by treating(6) with NaHCO3.RESULTS:The title compound is prepared successfully over 45% yield. The structure is characterized by elementary analysis,IR,MS,1H NMR,H-H COSY,13C NMR ,DEPT and HMQC. CONCLUSION:The method is simple and applicable to large scale preparation
