Pd/C 10% (500 mg) is added to a solution of the compound obtained in Step B (16.6 mmoles) in MeOH (100 ml). The reaction mixture is stirred at 50° C. under 4.5 bars of hydrogen for 4 hours. The catalyst is filtered off and then washed with MeOH. The filtrate is evaporated to dryness and the product obtained is triturated in 10 ml of MeOH. The solid obtained is filtered off and dried in vacuo at 40° C. overnight to yield the title product in the form of a white solid, which is used directly in the next Step.
