실험 절차

The title product of Example 2 (830 mg, 3.25 mmole) was dissolved in about 200 ml of boiling chloroform and then cooled to about −10° C. A solution of 662 mg (ca. 3.25 mmole) of ca. 85% m-chloroperoxybenzoic acid in 10 ml of chloroform was then added with stirring over about ten minutes. After another thirty minutes, the reaction was quenched with 4 drops of dimethylsulfide and a white solid was collected by filtration. The solid was washed sequentially with chloroform and diethyl ether, then air dried, giving 550 mg of the title compound: m.p. 164-165° C. Analysis. Calc'd. for C14H13N3OS*½ H2O: C,59.98; H,5.03; N, 15.00; S, 11.44. Found: C, 60.11; H, 4.82; N, 14.93; S, 11.44.
