Procedure

A 5.5 g portion of the compound of Example 22 was added to 50 ml of methanol containing 0.54 g of sodium, and the mixture was heated briefly to reflux. It was then cooled and the solvent was removed under vacuum. To it was added 75 ml of toluene, 2.6 ml of benzyl chloride and 2.3 g of triethylamine, and the mixture was heated under reflux for 22 hours. It was then cooled, poured over ice-water, and extracted with ethyl acetate. The extract was washed with water and with saturated brine, and was dried with sodium sulfate and phase separation paper. It was then evaporated under vacuum, and the residue was recrystallized from ethanol-water to obtain 2.5 g of the desired product, m.p. 78°-80°.
