Reaction Steps

110 ml of n-butanol, 240 ml of triethylamine and 236 g(1.60 mmole) of 1-methyl-1,2,3,4-tetrahydroisoquinoline were added to 600 ml of ethylene glycol. 400 g(1.59 mmole) of 4-chloro-2-(4-fluorophenylamino)-5,6-dimethylpyrimidine was added thereto and then reacted at 140° C. for 48 hours 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 485 g of purified 5,6-dimethyl -2-(4-fluorophenylamino)-4-(1-methyl-1,2,3,4-tetrahydroisoquinolin-2-yl)pyrimidine hydrochloride.
