実験手順
A solution of 30 g of 1-isopropyl-1-cyanohydrazine in 45 ml of methylene chloride is added dropwise, in the course of 5 hours, to a solution, cooled to 5° C, of 59 g of phosgene in 180 ml of methylene chloride. After completion of the addition, the temperature is allowed to rise to room temperature, and stirring is maintained for 24 hours, with 1-isopropyl-3-hydroxy-5-chloro-1,2,4-triazole precipitating out in crystalline form as hydrochloride. There is obtained 33 g (53.2% of theory) of 1-isopropyl-3-hydroxy-5-chloro-1,2,4-triazole hydrochloride, m.p. 138°-142° C.
