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-chlorophenyl)-5-(trifluoromethyl)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) δ 7.30-7.44 (m, 3H), 6.73-6.81 (m, 2H), 5.16 (s, 2H), 2.84 (t, J=7.5 Hz, 2H), 2.58 (t, J=7.5 Hz, 2H) Mass spectrum (ESI, m/z): Calcd. for C20H12ClF6NO3S, 496.0 (M+H). found 496.0.
