실험 절차

A suspension of 9.7 g (0.050 mol) of 5-chloromethyl-2-methyl-pyrimidin-4-ylamine hydrochloride, 9.8 g (0.050 mol) of 4-phenyl-1,2,3,6-tetrahydropyridine hydrochloride and 13.8 g (0.1 00 mol) of dry potassium carbonate in 125 ml of dimethylformamide was stirred vigorously at 80° for 5 hours. The mixture was cooled, suction filtered, completely freed from the solvents and the residue was triturated in water. The resulting crystals were filtered off under suction and recrystallized from ethanol/water. 3.0 g (21%) of 5-(4-phenyl-3,6-dihydro-2H-pyridin-1-ylmethyl)-2-methyl-pyrimidin-4-ylamine were obtained as yellow crystals; m.p. 165°-166°.
