Procedure

A solution of 100 mg. of the carboxylic acid prepared in Example 30 in 10 ml. of methylene chloride is combined dropwise with an ethereal diazomethane solution at 0° until the yellow coloring is permanent. After 5 minutes the mixture is evaporated under vacuum and the residue filtered with methylene chloride/2% isopropanol over silica gel, thus obtaining 95 mg. of the title compound as an oil.
