Reaction Steps

75 ml of triethylamine and 65 g(442 mmole) of 1-methyl-1,2,3,4-tetrahydroisoquinoline as prepared in Example 7 were added to 100 ml of 1,2-propylene glycol. 100.9 g(0.40 mmole) of 4-chloro-2-(4-fluorophenylamino)-5,6-dimethylpyrimidine was added thereto and then reacted at 120° C. for 64 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 21 to obtain 95.1 g of purified 5,6-dimethyl-2-(4-fluorophenylamino)-4-(1-methyl-1,2,3,4-tetrahydroisoquinolin-2-yl)pyrimidine hydrochloride.
