Reaction Conditions:

with Pd/C;hydrogen in tetrahydrofuran at 20; under 775.743 Torr; for 4 h;

Steps:

3 Step 3

To a solution of 1 -methyl-4-(3-nitrophenoxy)piperidine (320 mg, 1 .35 mmol, 1 .00 eq) in tetrahydrofuran (5.00 mL) was added Pd/C 10% weight on C ( 100 mg, 1 .00 eq). The reaction was stirred under hydrogen atmosphere ( 1 5 psi) at 20°C for 4 h. The mixture was filtered, and the filtrate was concentrated under reduced pressure to afford 3-[(1 -methyl-4- piperidyl)oxy]aniline (270 mg, 1 .31 mmol, 97% yield) as a yellow solid.
