실험 절차
4-(5-Benzyl-2-methyl-2H-pyrazol-3-yl)-piperidine-1-carboxylic acid tert-butyl ester (0.032 g) was dissolved in a 25% v/v solution of trifluoroacetic acid in DCM (7 mL) and stirred for 30 minutes. The solvents were then evaporated under reduced pressure to give a clear oil which was purified by column chromatography on SCX-2 stationary phase using a gradient of DCM up to 50% 7N NH3 in MeOH in DCM as eluent. Evaporation of solvent under reduced pressure gave the title compound as a clear oil (0.018 g); NMR(CDCl3): 1.50-1.60 (qd, 2H), 1.85 (br d, 2H), 2.64 (tt, 1H), 2.66-2.76 (qd, 2H), 3.17 (br d, 2H), 3.76 (s, 3H), 3.91 (s, 2H), 5.76 (s, 1H), 7.16-7.20 (m, 1H), 7.24-7.30 (m 4H); MS: 256 (MH+).
