Reaction Steps

A solution of 2,4-dichloro-6-methyl-thieno-[2,3-d]-pyrimidine (3.29 g) in dichloromethane (30 ml) is charged with 3,4-methylenedioxybenzylamine ("A") (3.02 g). Triethylamine (1.52 g) is added, and the mixture is stirred at room temperature. The solvent is removed, and the usual workup yields 2-chloro-6-methyl-4-(3,4-methylenedioxybenzylamino)-thieno-[2,3-d]-pyrimidine (3.38 g) Mp. 162° C.
