Versuchsvorschrift
To a 10 mL round bottomed flask was added 10 mg (0.009 mmol) of 10% palladium on activated carbon which was then flushed with nitrogen. Next, a solution of 0.090 (0.22 mmol) of benzyl 4-[2-(benzyloxy)pyridin-3-yl]piperazine-1-carboxylate from Step A above in 4 mL of methanol was added and the resulting mixture was placed under an atmosphere of hydrogen gas at atmospheric pressure for 3 h. The reaction was then flushed with nitrogen and filtered through a pad of Celite®. The pad was washed with methanol and the combined organics were evaporated to dryness to afford the title compound as a clear gum (0.035 g, 88%). LC-MS: m/z (ES) 180.1 (MH)+.
