実験手順

A flask containing 5% palladium on carbon (1.95 g) was evacuated and refilled with hydrogen. 4-(3-Nitrophenyl)morpholine (intermediate 2) (19.5 g, 93.75 mmol) was introduced into the flask as a solution in ethanol and dimethylformamide (1000 ml, 4:1 v/v). The reaction was stirred at room temperature until further uptake of hydrogen ceased (after approximately 7 L). The reaction was then filtered through celite and solvent removed in vacuo to yield the desired product (12.6 g, 70.6 mmol) as a beige solid.
