Procedure

The title compound was prepared according to the procedure described in Example 156 following Step 2 by LAH reduction of ethyl 3-(4-((3-chloro-5-(4-methoxyphenyl)isothiazol-4-yl)methoxy)-2,3-difluorophenyl)propanoate to afford the desired product as an off-white solid. 1H NMR (300 MHz, CD3OD): δ 7.53 (d, J=8.7 Hz, 2H), 7.08 (d, J=9.0 Hz, 2H), 6.87-7.00 (m, 2H), 5.07 (s, 2H), 3.60 (d, J=6.6 Hz, 2H), 2.18 (d, J=7.2 Hz, 2H), 1.78-1.87 (m, 2H). Mass spectrum (ESI, m/z): Calcd. for C20H18ClF2NO3S, 426.1 (M+H). found 426.1.
