Procedure
To 100 ml of tetrahydrofuran add the compound obtained in Step A (0.0175 mol) and then palladium-on-carbon (0.2 g). Stir at ambient temperature under hydrogen for 1 day. Filter off the palladium-on-carbon and then evaporate the filtrate. The oily product is purified on a column of silica gel using the eluant mixture: petroleum ether/dichloromethane (1/1). The title compound is obtained in the form of an oil.
