実験手順

10% Palladium on activated carbon (500 mg, 4.70 mmol, 1.09 eq) is added at room temperature to a stirred solution of acetic acid 4-acetoxy-3-(trans-4-tert-butoxycarbonylamino-cyclohexyl)-6-methoxy-3,4-dihydro-2H-1-oxa-9-aza-phenanthren-2-yl ester (2.3 g, 4.29 mmol, 1.0 eq) in methanol (60 mL). The reaction mixture is stirred at room temperature under hydrogen flow (10 bars) for 72 hours. The catalyst is then removed by filtration and the solution is concentrated to afford acetic acid 3-(trans-4-tert-butoxycarbonylamino-cyclohexyl)-6-methoxy-3,4-dihydro-2H-1-oxa-9-aza-phenanthren-2-yl ester as a yellow semisolid (1.45 g, 71% yield) which is directly engaged in the next step.
