Procedure

A mixture of the product from Step A (10.6 g, 27 mmol) and palladium-on-carbon (10%, 0.26 g) in methanol (250 mL) was stirred under an atmosphere of hydrogen for 6 h, dichloromethane (100 mL) was added and the mixture filtered. Evaporation of the filtrate gave an off-white solid (7.0 g, 85%): mp 169-174° C.; LC/MS (+APCI) m/z 307 (M+H).
