Reaction Steps

To a stirred mixture of 7-cyano-2-(3-methyl[1,2,4]thiadiazol-5-yl)heptanoic acid phenylamide (2021044) (0.55 g, 1.7 mmol) in pyridine (120 mL) and piperidine (30 mL) was slowly bubbled hydrogen sulphide for 15 min. The resultant mixture was then stoppered and stirred at 50° C. for five days. The solvent was removed under reduced pressure, water (150 mL) was added to the residue, and the resultant solution was extracted with dichloromethane (3×150 mL). The crude product (1.6 g) was purified by preparative liquid chromatography to afford 2-(3-methyl-[1,2,4]thiadiazol-5-yl)-7-thiocarbamoyl heptanoic acid phenylamide (2021036) as a white solid.
