A solution of 30 g of product from Example 81 in 150 ml of ethyl alcohol and 20 ml of ethyl acetate is treated with 2 g of 10% palladium/carbon in a Parr Hydrogenator for 18 hours. The reaction solution is filtered and concentrated in vacuo. The residue is recrystallized from hexane to give 25.7 g of the desired product as a white solid.
