Reaction Steps

by dissolving tert-butyl 3-(1-(2-(methylsulfonyl)acetyl)-3′H-spiro[azetidine-3,1′-isobenzofuran]-5′-yl)-5-(3,4,5-trichlorophenyl)-5-(trifluoromethyl)-4,5-dihydro-1H-pyrazole-1-carboxylate in dioxane (0.2M) and purged with HCl gas at 0° C. for 30 minutes. Reaction mixture was then stirred for 30 minutes at room temperature. After consumption of starting material, reaction mixture reaction mixture was concentrated in vacuo to get an orange semisolid. Crude was triturated with Chloroform:hexane (1:8) to afford title compound as off white solid. Yield: 105 mg (35%). 1H NMR (400 MHz, CDCl3) δ: 3.18 (s, 3H), 3.38 (d, J=17.2 Hz, 1H), 3.85-3.89 (m, 3H), 4.33 (d, J=9.8 Hz, 1H), 4.43 (d, J=11.08 Hz, 1H), 4.65 (s, 2H), 5.14 (s, 2H), 6.42 (s, 1H), 7.50-7.54 (m, 4H), 7.60-7.62 (d, J=7.8 Hz, 1H). LC-MS (m/z):=593.8 (M−H). HPLC 87.81%.
