実験手順

Benzyl 4-((1R,2S)-2-(2-(5-(methylsulfonyl)pyridin-2-yloxy)ethyl)cyclopropyl)piperidine-1-carboxylate (Intermediate 12; 1.20 g, 2.62 mmol) and palladium on activated carbon (10%, wet, 240 mg) in ethanol (50 mL) were stirred under an atmosphere of hydrogen (1 atm) at RT for 3 h. The mixture was filtered (glass wool filter paper, Whatman 1821 110), and washed with ethanol. The filtrate was concentrated to dryness under reduced pressure to provide the title compound as an off-white solid. 1H NMR (300 MHz, CDCl3) δ 8.72 (dd, J=0.5, 2.5 Hz, 1H), 8.03 (dd, J=2.5, 8.7 Hz, 1H), 6.84 (dd, J=0.6, 8.7 Hz, 1H), 4.48 (t, J=7.2 Hz, 2H), 3.20-3.05 (m, 2H), 3.07 (s, 3H), 2.65-2.50 (m, 2H), 2.20-1.90 (m, 2H), 1.85-1.65 (m, 2H), 1.60-1.45 (m, 1H), 1.45-1.20 (m, 2H), 1.00-0.80 (m, 2H), 0.70-0.60 (m, 2H), −0.13 (q, J=4.2 Hz, 1H). MS (Multimode) m/z 325 [M+H]+.
