Reaction Steps
45 ml of triethylamine, 50 ml of n-butanol and 32 g (217 mmole) of 1-methyl-1,2,3,4-tetrahydroisoquinoline were added to 150 ml of ethylene glycol. 51.3 g (203.8 mmole) of 4-chloro-2-(4-fluorophenylamino)-5,6-dimethylpyrimidine was added thereto and then reacted at 135° C. for 28 hours under refluxing to prepare 5,6-dimethyl-2-(4-fluorophenylamino)-4-(1-methyl-1,2,3,4-tetrahydroisoquinolin-2-yl)pyrimidine. This product was treated according to the procedure detailed in Example 14 to obtain 66 g of purified 5,6-dimethyl-2-(4-fluorophenylamino)-4-(1-methyl-1,2,3,4-tetrahydroiso-quinolin-2-yl)pyrimidine hydrochloride.
