A Parr hydrogenation shaker was charged with a solution of 29.76 g (187 mmol) of the product of Step A in 100 mL of ethanol and 3.00 g of a 10% palladium on carbon catalyst was added. The flask was mounted in the hydrogenation appartus, freed of air, pressurized with hydrogen (40 psig) and shaken 80 minutes. At the end of this preiod, TLC analysis (15% ethyl acetate/hexane) indicated that the reaction was complete and the reaction mixture was filtered and evaporated. The product was dried in vacuo to afford 30.01 g (99%) of the title compound as a yellow oil.
