Procedure
The title compound was prepared according to the procedure described in Example 197 by coupling of [5-chloro-3-(4-chlorophenyl)thiophen-2-yl]methanol and ethyl 3-(4-hydroxy-2,3-difluorophenyl)propanoate followed by hydrolysis of ethyl 3-(4-((5-chloro-3-(4-chlorophenyl)thiophen-2-yl)methoxy)-2,3-difluorophenyl)propanoate to afford the desired product as an off-white solid. 1H NMR (300 MHz, CD3OD) δ: 7.36-7.48 (m, 4H), 7.13 (s, 1H), 6.87-6.93 (m, 1H), 6.66-6.67 (m, 1H), 5.07 (s, 2H), 2.87 (t, J=7.5 Hz, 2H), 2.53 (t, J=7.8 Hz, 2H). Mass spectrum (ESI, m/z): Calcd. for C20H14C12F2O3S, 441.0 (M−H). found 441.0.
