Reaction Steps
200 ml of n-propanol was added to 30.0 g (0.16 mol) of 4-methoxyphenethylamine hydrochloride and 14.1 g (0.17 mol) of dicyanodiamide, and the mixture was refluxed for 24 hours, and cooled. The resulting precipitated crystals were filtered off, and the filtrate was concentrated and cooled. The precipitated crystals were recrystallized from n-propanol to obtain 22.6 g of colorless crystals having a melting point of 136 to 139° C.
