Procedure

To a solution of EXAMPLE 34A (3.7 g) in acetic acid (200 mL) was added 5% platinum on carbon (370 mg). The mixture was shaken under 60 psi of hydrogen until all starting material was consumed, filtered and concentrated. The concentrate was partitioned between ethyl acetate and saturated sodium bicarbonate solution. The extract was washed with water and concentrated.
