Participants

Reaction Steps

The title compound was prepared according to the procedure described in Example 207 by coupling of (3-(4-ethylphenyl)-5-methylthiophen-2-yl)methanol and ethyl 3-(4-hydroxy-2,3-dimethyl 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 7.35 (d, J=7.5 Hz, 2H), 7.26 (s, 1H), 7.18 (d, J=7.5 Hz, 2H), 6.95 (d, J=7.0 Hz, 1H), 6.64 (d, J=7.1 Hz, 1H), 5.05 (s, 2H), 2.95 (t, J=6.5 Hz, 2H), 2.68 (m, J=7.5 Hz, 2H), 2.58 (t, J=6.2 Hz, 2H), 2.51 (s, 3H), 2.21 (s, 3H), 2.20 (s, 3H), 1.26 (t, J=8.0 Hz, 3H).
