Example 2-2; THF, in an amount of 20 mL, was placed in a four-necked flask with a volume of 200 mL, and 10.95 g (purity: 98.7percent, 0.100 mol) of DAMN and 12.73 g (0.120 mol) of trimethyl orthoformate were added thereto. 27 mg of methanesulfonic acid was added to the aforementioned mixture, and the reaction mixture was stirred for one hour while maintaining the temperature at 40.deg.C. Thereby, a slurry of MMD was obtained. THF, in an amount of 15 mL, was added to the aforementioned slurry of MMD, followed by adding 27.25 g (0.400 mol) of 25percent aqueous ammonia thereto. The reaction mixture was stirred for one hour while maintaining the temperature at 30.deg.C. Thereby, a slurry of AMD-H was obtained. A 25percent aqueous solution of sodium hydroxide, in an amount of 32.00 g (0.200 mmol), was added to the slurry of AMD-H. The reaction mixture was stirred for one hour at 30 to 40.deg.C. A 35percent aqueous solution of hydrochloric acid, in an amount of 20.8 g (0.20 mol), was added to the obtained reaction liquid. As a result of quantitative analysis of AICN in the solution, AICN was contained in an amount of 9.43 g (0.0872 mol).
