The title compound was prepared according to the procedure described in Example 111 by LAH reduction of ethyl 3-(4-((3-(4-ethylphenyl)-5-(trifluoromethyl)isothiazol-4-yl)methoxy)-3,5-difluorophenyl)-2-methylpropanoate to afford the desired product as an off-white solid. 1H NMR (400 MHz, CD3OD) δ 7.71 (d, J=8.0 Hz, 2H), 7.35 (d, J=8.0 Hz, 2H), 6.78-6.84 (m, 2H), 5.21 (s, 2H), 3.41 (d, J=6.8 Hz, 2H), 2.71-2.79 (m, 3H), 2.30-2.36 (m, 1H), 1.82-1.91 (m, 1H), 1.30 (t, J=7.6 Hz, 3H), 0.89 (d, J=6.8 Hz, 3H). Mass spectrum (ESI, m/z): Calcd. for C23H22F5NO2S, 472.2 (M+H). found 472.2.
