A solution of 68 (1.056 g, 5.0 mmol) in 25 ml of acetic acid is hydrogenated over 1.056 g of platinum dioxide at RT and normal pressure for 18 hours. The black suspension is diluted with 20 ml of DCM and filtered through a pad of celite. The filtrate is evaporated to give 1.09 g of a yellow oil which is purified by chromatography (Silica gel 60, 0.063-0.2 mesh, ethyl acetate/ethanol 9:1).
