実験手順
To a suspension of 2-chloro-3,4-dihydro-6-(3,4-dimethoxyphenyl)-3-methyl-4-(2,4,6-trimethylphenylimino)pyrimidine (2.08 g) in ethanol (20 ml) was added 1,2,3,6-tetrahydropyridine (1.38 ml), and refluxed for 1.5 hours. The resulting precipitates were collected, dissolved in chloroform, washed with aqueous sodium bicarbonate solution, and dried over magnesium sulfate. After evaporated, the residue was triturated with diisopropyl ether to give 3,4-dihydro-6-(3,4-dimethoxyphenyl)-3-methyl-2-(1,2,3,6-tetrahydropyridin-1-yl)-4-(2,4,6-trimethylphenylimino)pyrimidine (1.95 g).
