This trans-4-pentylcyclohexanecarboxamidine hydrochloride (69 g, 0.30 mol) and dimethyl methoxymalonate (48 g, 0.30 mol) were added to a solution of sodium methylate (56 g, 1.0 mol) dissolved in anhydrous methanol (1 l), followed by heating the mixture under reflux with stirring for 5 hours, thereafter cooling the resulting material, mixing it with 6N-hydrochloric acid (500 ml), agitating the mixed liquid at room temperature for 20 minutes, filtering the liquid under suction through a filter, washing the resulting residue on the filter with water and methanol and drying it under reduced pressure to obtain 2-(trans-4-pentylcyclohexyl)-4,6-dihydroxy-5-methoxypyrimidine (67 g, 0.23 mol).
