Procedure
Suspend 1.14 gm (4 mmole) of the ester of Example 23 in 60 ml of methylene chloride and add 1.035 gm of commercial m-chloroperbenzoic acid. Stir at room temperature for 45 minutes and filter. Concentrate the filtrate and separate the solids. Combine the solids to obtain the title product (yield 1.21 gm).
