Procedure
5 g of the product of Stage A, 50 ml of methanol, 25 ml of acetic acid and 150 ml of water were stirred for 30 hours at ambient temperature under a hydrogen atmosphere (400 mbar) in the presence of 2 g of 20% palladium hydroxide on wet activated charcoal (50% water). Filtration was carried out followed by washing with methanol, then concentrating to dryness under reduced pressure at 40° C. After crystallization from ethyl acetate, 3 g of the expected product were obtained.
