Reaction Steps

A solution containing the product from Example 120A (0.028 g, 0.041 mmol) in methanol (1 mL) was treated with 10% Pd on carbon (0.003 g) and HCl solution (0.030 mL, 4 N in dioxane), and the reaction was stirred under a hydrogen atmosphere (balloon pressure) at 25° C. for 16 hours. The reaction was filtered through a bed of celite and rinsed with methanol. The solvent was concentrated to give the title compound as the hydrochloride salt, which was used without further purification.
