Procedure
The title compound was prepared according to the procedure described in Example 1 starting following Step 5 and 6 coupling (3-(2-fluoro-4-methoxyphenyl)-5-(trifluoromethyl)isothiazol-4-yl)methyl methanesulfonate and ethyl 3-(4-hydroxy-3,5-difluorophenyl)propanoate followed by hydrolysis to afford the desired product as an off-white solid. 1H NMR (300 MHz, CD3OD) δ 7.25-7.30 (m, 1H), 6.70-6.83 (m, 4H), 5.15 (s, 2H), 3.87 (s, 3H), 2.82 (t, J=7.8 Hz, 2H), 2.57 (t, J=7.8 Hz, 2H). Mass spectrum (ESI, m/z): Calcd. for C21H17F6NO4S, 490.1 (M−H). found 489.9.
