Procedure

The title compound was prepared according to the procedure described in Example 196 by coupling of [5-chloro-3-(4-ethylphenyl)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 (400 MHz, CDCl3) 7.26-7.33 (m, 4H), 6.95 (s, 2H), 6.85 (t, J=8.8 Hz, 2H), 6.59-6.64 (t, J=8.4 Hz, 1H), 6.62 (t, J=8.4 Hz, 1H), 5.13 (s, 2H), 2.96 (t, J=7.8 Hz, 2H), 2.67-2.74 (m, 4H), 1.29 (t, J=7.6 Hz, 3H). Mass spectrum (ESI, m/z): Calcd. for C22H19ClF2O3S, 435.1 (M−H). found 435.1.
