To 5-methoxy-2-(4-octylphenyl)pyrimidine (53.9 g, 0.18 mol) were added diethylene glycol (500 ml) and NaOH (43.4 g, 1.08 mol), followed by agitating the mixture at about 200° C. for 2 hours, pouring the resulting material in acetic acid (700 ml), collecting deposited crystals and recrystallizing the crystals from a mixed solvent of heptane (100 ml) with ethyl acetate (10 ml) to obtain 5-hydroxy-2-(4-octylphenyl)pyrimidine (45.2 g) (m.p.:147.3°-148.7° C.).
