Procedure
The title compound was prepared according to the procedure described in Example 1 starting following Step 5 and 6 coupling (5-(trifluoromethyl)-3-(2,6-difluoro-4-methoxyphenyl) isothiazol-4-yl)methyl methanesulfonate and ethyl 3-(4-hydroxy-2,3-dimethylphenyl)propanoate followed by hydrolysis to afford the desired product as an off-white solid. 1H NMR (300 MHz, CDCl3) δ 6.93 (d, J=8.4 Hz, 1H), 6.52-6.59 (m, 3H), 5.02 (s, 2H), 3.85 (s, 3H), 2.94 (t, J=7.2 Hz, 2H), 2.60 (t, J=7.5 Hz, 2H), 2.20 (s, 3H), 1.97 (s, 3H). Mass spectrum (ESI, m/z): Calcd. for C23H20F5NO4S, 502.1 (M+H). found 502.1.
