Procedure

A solution of 65 (225 mg, 1.0 mmol) in 5 ml of acetic acid is hydrogenated over 225 mg of platinum dioxide at RT and normal pressure for 18 hours. Another 225 mg of platinum dioxide is added and hydrogenation continued for 24 hours. The black suspension is diluted with 10 ml of DCM and filtered through a pad of celite. The filtrate is evaporated to give 268 mg of a yellow oil which is purified by chromatography (Biotage 12Si, I=7.5 cm, ethyl acetate/ethanol 9:1).
