実験手順
Dissolve 2 gm (0.0071 moles) of the ester of Example 2 in 200 cc of chloroform and 1.396 gm of m-chloroperbenzoic acid and stir at room temperature for 20 minutes. Add successive 100 mg portions of m-chloroperbenzoic acid until thin layer chromatography slows conversion of the starting material. Basify with calcium hydroxide and separate the solids. Chromotograph the solids over silica gel eluting with 30% ethyl acetate in benzene to obtain the title product (yield 870 mg).
