Procedure

To a 160 ml Parr stirrer hydrogenation vessel was added the product from Example 37D (2 g, 4.49 mmol), followed by 60 ml of THF, and Raney Nickel Grace 2800 (1 g, 50 wt % (dry basis)) under a stream of nitrogen. The reactor was assembled and purged with nitrogen (8×20 psig) followed by purging with hydrogen (8×30 psig). The reactor was then pressurized to 30 psig with hydrogen and agitation (700 rpm) began and continued for a total of 16 h at room temperature. The slurry was filtered by vacuum filtration using a GF/F Whatman glass fiber filter. Evaporation of the filtrate to afford a slurry followed by the addition heptane and filtration gave the crude title compound, which was dried and used directly in the next step.
