PROCESS FOR PREPARATION OF PYRIMIDINE DERIVATIVES

摘要

The present invention relates, first to a process for preparation of 5,6-dimethyl-2-(4-fluorophenylamino)-4-(1-methyl-1,2,3,4-tetrahydroisoquinolin-2-yl)pyrimidine represented by formula (I) and its acid addition salts, second, to a process for preparation of an intermediate for preparing the compound (I), and, third, to a novel intermediate compound. More specifically, the present invention relates, first, to a process for preparation of 5,6-dimethyl-2-(4-fluorophenylamino)-4-(1-methyl,1,2,3,4-tetrahydroisoquinolin-2-yl)pyrimidine represented by formula (I), and its acid addition salts by reacting a pyrimidine derivative represented by formula (II-A), in which Hal represents a halogen, with 1-methyl-1,2,3,4-tetrahydroisoquinoline represented by formula (III), second, to a process for preparating of the pyrimidine derivative of formula (II-A) and the compound of formula (III); and, third, to a novel intermediate compound including the pyrimidine derivative of formula (II-A).
