Procedure

Metal sodium (23.4 g, 1.02 mol) was added to methanol (500 ml) to obtain sodium methoxide, followed by adding thereto 4-octylbenzamidine hydrochloride (84 g, 0.31 mol) and dimethyl methoxymalonate (55 g, 0.31 mol), refluxing the mixture for 8 hours, pouring the reaction mixture in acetic acid (500 ml), filtering off deposited crystals, washing them with water and drying to obtain 4,6-dihydroxy-5-methoxy-2-(4-octylphenyl)pyrimidine (91.5 g).
