Procedure

A solution containing 0.2 g of the compound obtained in Step A and 0.09 g of Pd/C in 5 ml of ethanol is stirred at ambient temperature under an H2 atmosphere for 48 hours. The catalyst is then filtered off and the filtrate is concentrated in vacuo. The residue is chromatographed over silica (dichloromethane/methanol: 95/5), allowing the desired product to be isolated.
