Triethylamine → Revaprazan Hydrochloride

Participants

Reaction Steps

8.12 g (11.2 ml, 80.3 mmole) of triethylamine, 30 ml of n-butanol and 6.58 g (44.1 mmole) of 1-methyl-1,2,3,4-tetrahydroisoquinoline were added to 40 ml of ethylene glycol. 10.1 g (40.1 mmole) of 4-chloro-2-(4-fluorophenylamino)-5,6-dimethylpyrimidine was added thereto and then reacted at 130° C. for 30 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 14.7 g of purified 5,6-dimethyl-2-(4-fluorophenylamino)-4-(1-methyl-1,2,3,4-tetrahydroisoquinolin-2-yl)pyrimidine hydrochloride.
