Procedure
The title compound was prepared according to the procedure described in Example 91 following Step 5 and 6 by coupling (3-(5-chlorothiophen-2-yl)isothiazol-4-yl)methyl methanesulfonate and ethyl 3-(4-hydroxy-2,3-dimethylphenyl)propanoate followed by hydrolysis to afford the desired product as an off-white solid. 1H NMR (400 MHz, CDCl3) δ 8.70 (s, 1H), 7.19 (s, 1H), 7.03 (d, J=5.5 Hz, 1H), 6.89 (s, 1H), 6.76 (d, J=5.5 Hz, 1H), 5.15 (s, 2H), 2.96 (t, J=5.0 Hz, 2H), 2.62 (t, J=5.1 Hz, 2H), 2.24 (s, 3H), 2.18 (s, 3H).
