実験手順
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 DCM (4 mL) was added oxalyl chloride (0.030 g, 0.0.243 mmol) at 0° C. and stirred for 1 hour under nitrogen atmosphere at room temperature. After 1 hour, saturated solution of methyl amine (4 mL) was added. Resulting reaction mixture was stirred at room temperature for 16 hours. After complete consumption of starting material, reaction mixture was concentrated in vacuo to get crude. Crude was purified by column chromatography on silica gel (100-200 mesh). Compound was eluted using 0.7% methanol in DCM to afford pale yellow solid (0.055 g, 54%). 1H-NMR (400 MHz, CDCl3) δ: 2.86-2.90 (d, 3H, J=4.84 Hz), 3.36-3.39 (m, 1H), 3.61 (d, 1H, J=17 Hz), 4.01-4.09 (m, 5H), 5.62-5.63 (m, 1H), 6.40-6.42 (m, 2H), 7.46-7.50 (m, 2H), 7.63 (s, 2H); LC-MS (m/z): [M−H] 503.80. HPLC purity: 96.77%.
