Reaction Steps

To 1-[3-(methyloxy)-4-nitrophenyl]-4-{1-[2-(methylsulfonyl)ethyl]-4-piperidinyl}piperazine (1.18 g, 2.76 mmol) in EtOAc (100 mL) and EtOH (25 mL) was added Pd on carbon in one portion. The mixture was stirred at rt under H2 (1 atm.) until complete by TLC. The reaction was filtered through Celite® and concentrated. Purification by flash chromatography provided the title compound of step F (0.690 g, 1.75 mmol, 63%). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.31-1.42 (m, 2H), 1.75 (d, J=11.4 Hz, 2H), 1.86-1.97 (m, 2H), 2.15 (tt, J=11.3, 3.9 Hz, 1H), 2.54-2.59 (m, 4H), 2.65 (t, J=6.8 Hz, 2H), 2.88-2.94 (m, 6H), 3.00 (s, 3H), 3.25 (t, J=6.8 Hz, 2H), 3.71 (s, 3H), 4.18 (br. s., 2H), 6.25 (dd, J=8.4, 2.6 Hz, 1H), 6.46 (d, J=2.6 Hz, 1H), 6.49 (d, J=8.4 Hz, 1H).
