Reaktionsschritte

To a solution of {4-[4-(5-Nitropyridin-2-yl)-phenyl]-cyclohexyl}-acetic acid methyl ester (1.4 g, 4.0 mmol) in 20 Ml EtOH was added Pd/C (0.4 g) followed by ammonium formate (2 g). The reaction mixture was heated to reflux for 4 h, then cooled to room temperature and filtered through Celite. Removal of solvent in vacuo afforded the title compound: 1H NMR (400 MHz, DMSO-d6) δ ppm 1.08-1.20 (m, 2H) 1.43-1.54 (m, 1H) 1.48 (dd, J=12.57, 2.46 Hz, 2H) 1.81 (d, J=11.75 Hz, 6H) 2.26 (d, J=6.69 Hz, 2H) 3.61 (s, 3H) 6.98 (dd, J=8.59, 2.78 Hz, 1′H) 7.24 (d, J=8.34 Hz, 2H) 7.57 (d, J=8.59 Hz, 1H) 7.81 (d, J=8.34 Hz, 2H) 8.00 (d, J=2.65 Hz, 1H); (M+H)+325.2.
