Reaction Steps
A mixture of 3-(3-chloropropyl)-5-methyl-2,4(1H,3H)-pyrimidinedione (223 mg, 0.98 mmol), prepared as in Example 19, and 1-(4-chloro-2-methoxyphenyl)piperazine (200 mg, 0.98 mmol), prepared as in Example 12, was heated 2 hours with stirring at 180° to 190° C., allowed to cool to 25° C. and then purified by preparative thin layer chromatography on silica gel eluting with methylene chloride/(methylene chloride/methanol/ammonium hydroxide-60:10:1) (7:3) to give 3-{3-[4-(4-chloro-2-methoxyphenyl)piperazin-1-yl]propyl}-5-methyl-2,4(1H,3H)-pyrimidinedione. The free base was recrystallized from a solution of hydrogen chloride in methanol to give 3-{3-[4-(4-chloro-2-methoxyphenyl)piperazin-1-yl]propyl}-5-methyl-2,4(1H,3H)-pyrimidinedione hydrochloride, m.p. 182°-184° C. Anal.: Calcd. for C19H25ClN4O3.(HCl)2 : C, 48.25; H, 5.92; N, 11.84%; Found: C, 48.55; H, 5.81; N, 11.85%.
