Participants

Reaction Steps

The title compound was prepared according to the procedure described in Example 196 step 7 by coupling of (3-(4-ethylphenyl)-5-methylthiophen-2-yl)methanol and ethyl 3-(4-hydroxy-3,5-difluoro phenyl)propanoate followed by hydrolysis of ethyl 3-(4-((3-(4-ethylphenyl)-5-methylthiophen-2-yl)methoxy)-3,5-difluorophenyl)propanoate to afford the desired product as an off-white solid. 1H NMR (400 MHz, CDCl3) δ 7.38 (d, J=7.0 Hz, 2H), 7.21 (d, J=7.1 Hz, 2H), 6.88 (s, 1H), 6.75 (d, J=7.8 Hz, 2H), 5.10 (s, 2H), 2.85 (t, J=7.5 Hz, 2H), 2.65 (t, J=7.0 Hz, 2H), 2.45 (s, 3H), 2.01 (m, J=7.8 Hz, 2H), 1.25 (t, J=7.2 Hz, 3H).
