Method 1 A solution containing the product from Example 23J (0.568 g, 0.95 mmol) in a mixture of ethyl acetate (5 mL) and methanol (5 mL) was treated with Pd(OH)2 on carbon (0.2 g, 20% Pd by wt.) and HCl solution (0.25 mL, 4N in dioxane), stirred under a hydrogen atmosphere (balloon pressure) for 16 hours at 25° C., filtered through a bed of celite®, rinsed with a mixture of 50% ethyl acetate in methanol, and concentrated. The residue was partitioned between ethyl acetate and saturated NaHCO3. The organic phase was washed with brine and dried over MgSO4, filtered and concentrated to give the title compound (0.442 g), which was used without further purification.
