実験手順
To a stirred solution of 4-(3-methoxy-4-nitro-phenoxy)-1-methyl-piperidine (Intermediate 44; 12.86 g, 48.34 mmol) in ethanol (250 mL) under nitrogen was added in one portion the Pd/C catalyst (10%, 1.29 g). The resulting mixture was evacuated and backfilled with nitrogen 4× before hydrogen gas was introduced via a balloon. The reaction mixture was stirred at room temperature for 18 hrs. The catalyst was removed by filtration through celite and the filtrate concentrated under reduced pressure to give a light red oil (11.1 g, 47.0 mmol, 97%).
