1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → 3-Chloropyridin-2-carboxylic acid (2-mercapto-5-trifluoromethylpyridin-3-yl)-amide

참여 물질

반응 단계

A mixture of 3-amino-5-trifluoromethylpyridin-2-thiol (0.45 g), 3-chloropyridin-2-carboxylic acid (0.39 g), WSC (0.67 g), HOBt (31 mg) and pyridine (4 ml) was stirred at room temperature for 12 hours. To the reaction mixture was added water, and the mixture was filtered to collect a solid. The resulting solid was washed with water, followed by n-hexane, and dried to give 3-chloropyridin-2-carboxylic acid (2-mercapto-5-trifluoromethylpyridin-3-yl)-amide (0.45 g), which is hereinafter referred to as “intermediate compound (M20-11)”.
