Procedure

To a degassed solution of compound 127 (100 mg, 0.209 mmol) in a mixture of methanol and ethyl acetate (1:1) was added was added a catalytic amount of 10% palladium on charcoal and the mixture was put under H2 atmosphere (latm) and stirred for 1 h and filtered through celite and the filtrate was concentrated in vacuo. The mixture was separated by flash chromatography on silica gel using EtOAc/Hexanes with increasing polarity (40:60 to 60:40) as the eluent. The least polar compound 129 was isolated as a white solid (31 mg, 31% yield) and the most polar compound was further purified by crystallization from a mixture of ethyl acetate and hexanes affording compound 128 as light beige crystals (18 mg, 18% yield).
