To a solution of 4-[3-(methyloxy)-4-nitrophenyl]-1-(2-methylpropyl)-1,2,3,6-tetrahydropyridine (1.90 g, 0.0655 mmol) in MeOH was added 10% Pd/carbon (0.800 g). The resulting suspension was stirred at rt under 60 psi H2 overnight. Subsequent filtration through celite and concentration under reduced pressure afforded {2-(methyloxy)-4-[1-(2-methylpropyl)-4-piperidinyl]phenyl}amine (1.7 g, 89% yield) as a dark brown solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 6.63 (s, 1H), 6.51 (s, 2H), 4.44 (s, 2H), 3.72 (s, 3H), 2.87 (d, J=11.36 Hz, 2H), 2.22-2.33 (m, J=11.82, 7.79, 4.03, 3.85 Hz, 1H), 2.01 (d, J=7.33 Hz, 2H), 1.88 (td, J=11.55, 2.57 Hz, 2H), 1.75 (dt, J=13.66, 6.92 Hz, 1H), 1.60-1.67 (m, 2H), 1.56 (dd, J=12.28, 3.48 Hz, 2H), 0.84 (d, J=6.60 Hz, 6H).
