실험 절차
To a solution of 4-aminomethyl-1-propyl-5-tritylaminopyrazole (9.6 g) in a mixture of ethyl acetate (150 ml) and methanol (30 ml) was added 4N hydrochloric acid in ethyl acetate (24.2 ml), and the mixture was stirred at room temperature for 2 hours. The resulting precipitate was collected by filtration and dried in vacuo to give 4-aminomethyl-1-propyl-5-aminopyrazole dihydrochloride (3.3 g).
