実験手順

In the same way as described for Compound 150, step 1, using 1-methyl-4-(4-nitro-phenoxymethyl)-piperidine (0.65 g, 2.6 mmol) in ethanol (40 mL) and palladium hydroxide (0.182 g, 0.26 mmol). Filtration over Celite 521 and evaporation gave a red oil that was purified by silica gel column chromatography eluting with DCM and a 80:20 mixture DCM:MeOH. The title compound was obtained as a white solid (0.402 g, 70%). 1H-NMR (400 MHz, CDCl3) δ (ppm) 1.30-1.51 (2H, m), 1.65-1.88 (3H, m), 1.89-2.09 (2H, t), 2.29 (3H, s), 2.90 (2H, d), 3.45 (2H, br s), 3.73 (2H, d), 6.67 (2H, d), 6.75 (2H, d).
