실험 절차

A mixture of 11.5 g. (50 mmole) methyl 4-bromomethylbenzoate, 11.3 g. (50 mmole) 1-benzenesulphonylpiperazine, 6.91 g. (50 mmole) powdered potassium carbonate and 100 ml. butan-2-one is maintained at reflux temperature for 20 hours, then suction filtered while hot and the filtrate evaporated. After cooling, the product is filtered off with suction and recrystallised from methanol to give 11.6 g. (62% of theory) of the desired product; m.p. 145°-146° C.
