Procedure
The title compound was prepared according to the procedure described in Example 1 starting following Step 5 and 6 coupling (5-(trifluoromethyl)-3-(3-methoxyphenyl)isothiazol-4-yl)methyl methanesulfonate and ethyl 3-(3,5-difluoro-4-hydroxyphenyl)propanoate followed by hydrolysis to afford the desired product as an off-white solid. 1H NMR (300 MHz, CD3OD) δ7.40 (t, J=7.8 Hz, 1H), 7.24-7.31 (m, 2H), 7.06-7.11 (m, 1H), 6.82 (d, J=13.5 Hz, 2H), 5.23 (s, 2H), 3.84 (s, 3H), 2.87 (t, J=7.2 Hz, 2H), 2.60 (t, J=7.5 Hz, 2H). Mass spectrum (ESI, m/z): Calcd. for C21H16F5NO4S, 474.1 (M+H). found 474.0.
