Participants

Procedure

1.09 g (20 mmol) sodium methoxide in 20 mL ethanol are added to a solution of 1.91 g (20 mmol) acetamidine hydrochloride in 30 mL ethanol. The mixture is stirred for 30 minutes at ambient temperature and then filtered. The filtrate is combined with 2.3 g (13.5 mmol) 4-chlorobenzoic acid hydrazide, stirred overnight at ambient temperature, cooled with an ice bath and then filtered. The precipitate is washed with cold ethanol and dried. Yellow solid. Yield: 1.45 g (51%); mass spectroscopy [M+H]+=212/214.
