실험 절차

A mixture of 4-(1,3-diethyl-2,3,6,7-tetrahydro-2,6-dioxo-1H-purin-8-yl)benzenesulfonic acid (5.0 g, 0.014 moles) and N,N-dimethylformamide (150 ml) is cooled to 0° and treated with thionyl chloride (3.3 g, 0.027 moles). When the addition is complete, the reaction mixture is permitted to warm to ambient temperature and stirred vigorously until a thick slurry results. To this slurry is added N-methylpiperazine (13.7 g, 0.137 moles) in one portion, the mixture is stirred until a clear solution is obtained, and concentrated on a rotary evaporator. The residue is taken up in water, filtered, recrystallized from ethanol, and dried at 48° to yield 5.12 grams of 1-[[4-(1,3-diethyl-2,3,6,7-tetrahydro-2,6-dioxo-1H-purin-8-yl)phenyl]sulfonyl]4-methylpiperazine, mp 305°-307° C.
