Reaction Steps

A mixture of pyridine-2-carbothioamide (5.00 g) and ethanol (15 mL) was heated at 50° C. Methyl 2-chloro-3-oxobutanoate (4.41 mL) was slowly added to this solution over 10 minutes. The solution was heated at 70° C. for 18 hours. The solution was cooled to room temperature and 50% ethanol (20 mL) was added. The solution was cooled to 0° C. and stirred for 1 hour. The solution was filtered and dried over vacuum to obtain the title compound (4.90 g) with the following physical data.
