Reaction Steps

A solution of the title compound of Step (1) (2.8 g) in a mixture of methanol (180 ml) and acetic acid (75 ml) was hydrogenated at atmospheric pressure in the presence of 10% palladium-carbon (2.0 g) until no further uptake of hydrogen was observed. The reaction mixture was then filtered and the filtrate was evaporated to dryness. The solid residue was crystallized to give the title compound (1.4 g). That the expected product was obtained was confirmed by the spectral data: MS: m/e 267 (M.+).
