A solution of 2-chloro-6-methyl-4-(3,4-methylene dioxybenzylamino)-thieno-[2,3-d]-pyrimidine (1.67 g), imidazole (1.02 g) and phenol (2 g) are heated 5 hours at 150° C. After cooling, the residue is dissolved in CH2Cl2. The solvent is removed, and the usual workup yields 2-(imidazol-1-yl)-6-methyl-4-(3,4-methylenedioxybenzylamino)-thieno-[2,3-d]-pyrimidine (3.38 g) Mp. 162° C.
