Procedure
A mixture of 1.5 g of methyl 4-(4-chlorobenzothieno[2, 3-d]pyrimidin-2-yl)phenylcarboxylate (“B”), prepared by dehydrogenation of the corresponding 5,6,7,8-tetrahydrobenzothieno[2,3-d]pyrimidine compound with sulfur and subsequent chlorination with phosphorus oxychloride/dimethylamine, and 1.5 g of 3-chloro-4-methoxybenzylamine in 20 ml of N-methylpyrrolidone is heated at 110° for 4 hours. After cooling, the mixture is worked up in the customary manner. 2.6 g of methyl 4-[4-(3-chloro-4-methoxybenzylamino)benzothieno[2,3-d]pyrimidin-2-yl]-benzoate, m.p. 203-204°, are obtained.
