Reaction Steps
Analogously to the procedure of example 42A, 1.95 g (4.42 mmol) of the compound from example 49A are hydrogenated in 120 g of ethanol using 200 mg of 10% Pd/C. Chromatography on 400 ml of silica gel using cyclohexane and ethyl acetate in a gradient system from 90:10 to 40:60 gives 1.26 g (69.4% of theory).
