Procedure

A mixture of N-(1-methylethyl)cinnamoylcarboxamide (18 g.), m-chloroperbenzoic acid (23.6 g.), 4,4'-thiobis(6-tert-butyl-m-cresol) (0.3 g.) and ethylene dichloride (250 ml.) was heated under gentle reflux for 1 hour, then chilled in ice. A precipitate (m-chlorobenzoic acid) was separated by filtration and washed with ethylene dichloride. The filtrate and washings were combined, and evaporated under reduced pressure on a rotary evaporator to give an amber oil. The oil was dissolved in chloroform (300 ml.) and the chloroform solution was washed with 5% aqueous sodium bicarbonate solution twice, then with saline. The chloroform solution was dried over magnesium sulfate, then evaporated under reduced pressure in a rotary evaporator to give an oil. The oil solidified on standing. The solid mass was recrystallized from ether giving 8.4 g. of product, m.p. 114°-115°.
