Reaction Steps

To a stirred solution of 3-fluoro-3-{4-[5-(3,4,5-trichloro-phenyl)-5-trifluoromethyl-4,5-dihydro-isoxazol-3-yl]-phenyl}-cyclobutanecarboxylic acid (Preparation 7, 0.085 g, 0.166 mmol) in DCM (4 mL) was added oxalyl chloride (0.025 g, 0.199 mmol) at 0° C. and stirred for 1 hour. After 1 hour, saturated solution of dimethyl amine in THF (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 afford crude. Crude was purified by column chromatography on silica gel (100-200 mesh size). Compound was eluted using 0.7% methanol in DCM to afford off white solid (0.026 g, 29%). 1H-NMR (400 MHz, CDCl3) δ: 2.72-2.78 (m, 2H), 2.87-2.92 (m, 1H), 2.94 (s, 3H), 2.98 (s, 3H), 2.99-3.09 (m, 2H), 3.68 (d, 1H, J=17.2 Hz), 4.08 (d, 1H, J=17.16 Hz), 7.54 (d, 2H, J=8.16 Hz), 7.64 (s, 2H), 7.70 (d, 2H, J=8.24 Hz); LC-MS (m/z): [M−H] 534.60.
