Reaction Steps

A solution of 1-(cyclopropylmethyl)-4-[3-(methyloxy)-4-nitrophenyl]piperazine (1.05 g, 3.41 mmol), FeCl3 (0.165 g, 1.02 mmol), activated carbon (1.0 g), and hydrazine hydrate (1.3 mL, 41 mmol) was heated in methanol (50 mL) for 3 hours. Once the starting material was judged consumed by thin layer chromatography (10% MeOH/CH2CL2) the mixture was filtered over celite and concentrated to give 4-[4-(cyclopropylmethyl)-1-piperazinyl]-2-(methyloxy)aniline as a yellow solid (0.800 g, 3.07 mmol, 90% yield). 1H NMR (400 MHz, CDCl3) δ ppm 0.15 (q, J=4.89 Hz, 2 H), 0.52-0.60 (m, 2 H), 0.94 (d, J=6.23 Hz, 1 H), 2.35 (d, J=6.59 Hz, 2 H), 2.74 (s, 4 H), 3.07-3.15 (m, 4 H), 3.53 (s, 2 H), 3.83 (s, 3 H), 6.43 (dd, J=8.43, 2.20 Hz, 1 H), 6.53 (d, J=2.20 Hz, 1 H), 6.65 (d, J=8.06 Hz, 1 H).
