Procedure
The title compound was prepared according to the procedure described in Example 1 starting following Step 5 and 6 coupling (5-(trifluoromethyl)-3-(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, CD3OD) δ: 7.65 (d, J=6.9 Hz, 2H), 6.96-7.02 (m, 3H), 6.72 (d, J=8.4 Hz, 1H), 5.13 (s, 2H), 3.55 (s, 3H), 2.92 (t, J=8.4 Hz, 2H), 2.51 (t, J=8.1 Hz, 2H), 2.28 (s, 3H), 2.07 (s, 3H). Mass spectrum (ESI, m/z): Calcd. for C23H22F3NO4S, 466.1 (M+H). found 466.1.
