실험 절차

To a stirred solution of 1-{4-[5-(3,4,5-trichloro-phenyl)-5-trifluoromethyl-4,5-dihydro-isoxazol-3-yl]-phenyl}-azetidine-3-carboxylic acid (Preparation 12, 0.1 g, 0.203 mmol) in DMF (3 mL) was added HOBt (0.027 g, 0.203 mmol), DIPEA (0.052 g, 0.406 mmol), EDCl.HCl (0.058 g, 0.304 mmol) and cyclopropyl amine (0.011 g, 0.203 mmol) at 0° C. Resulting reaction mixture was stirred at room temperature for 16 hours under nitrogen atmosphere. After complete consumption of starting material, reaction mixture was quenched with water (20 mL) and extracted with EtOAc (3×20 mL). Combined organic layer was washed with saturated NaHCO3 (2×50 mL), water (2×50 mL), brine (50 mL), dried over sodium sulphate and evaporated in vacuo to crude. Crude was purified by column chromatography on silica gel (100-200 mesh size). Compound was eluted using 1.1% methanol in DCM to afford white solid (0.036 g, 33%). 1H-NMR (400 MHz, CDCl3) δ: 0.49-0.53 (m, 2H), 0.77-0.87 (m, 2H), 2.74-2.77 (m, 1H), 3.31-3.34 (m, 1H), 3.61 (d, 1H, J=16.88 Hz), 4.01-4.07 (m, 5H), 5.72 (bs, 1H), 6.40 (d, 2H, J=8.68 Hz), 7.47 (d, 2H, J=8.68 Hz), 7.63 (s, 2H). LC-MS (m/z): [M−H] 529.70.
