Procedure

A stirred mixture of 14.0 g (0.039 mole) of product of Example 99, 105 ml of ethanol, 70 ml (0.60 mole) of 30% hydrogen peroxide, and 2.9 g (0.033 mole) of sodium bicarbonate is heated at 70° C. for 3 hours. The reaction mixture is cooled and concentrated in vacuo to approximately 30 ml then extracted with 75 ml of methylene chloride. The methylene chloride solution is washed with 300 ml of water. The aqueous layer is extracted twice with 75 ml of methylene chloride. The combined methylene chloride extracts were dried over magnesium sulfate and concentrated. The residue is purified by HPLC using 8% ethyl acetate/cyclohexane as eluent to give a yellow solid which after recrystallization from hexane/ether gave 2.32 g of the desired product as a white solid; m.p. 57.5°-59° C.
