Reaktionsschritte

To a solution of 6-(3,4-dimethoxyphenyl)-3-methyl-1,2,3,4-tetrahydro-4-(2,4,6-trimethylphenylimino)pyrimidine (1.0 g) in pyridine (10 ml) was added methyl isocyanate (0.18 ml), and the mixture was stirred at ambient temperature for 3 hours. Then the mixture was poured into water (150 ml), and the resultant precipitates were collected. The precipitates were washed with water, and dried to give 6-(3,4-dimethoxyphenyl)-3-methyl-1-(N-methylcarbamoyl)-1,2,3,4-tetrahydro-4-(2,4,6-trimethylphenylimino)pyrimidine (0.99 g).
