反応手順

A flask containing 6-methoxy-1,2,3,4-tetrahydroquinoline (1.33 g), 2-amino-4-chloro-6-methylpyrimidine (1.00 g), sulfuric acid (0.6 g), and 100 mL of water was heated on a steam bath for 2 hours. The solution was then cooled to room temperature and treated with ammonium hydroxide until the solution was basic (pH 8-9). The resultant solid, which precipitated from solution, was collected by filtration and recrystallized from ethyl alcohol to give 2-amino-4-(6-methoxy-3,4,-dihydro-2H-quinolin-1-yl)-6-methylpyrimidine (0.93 g), m.p. 175.2°-175.9° C.
