HCID 85472223HCID 85472223, compound

Procedure

The title compound was prepared according to the procedure described in Example 1 starting following Step 5 and 6 coupling (3-(2-fluoro-4-methylphenyl)-5-(trifluoromethyl)isothiazol-4-yl)methyl methanesulfonate and ethyl 3-(3,5-difluoro-4-hydroxyphenyl)propanoate followed by hydrolysis to afford the desired product as an off-white solid. 1H NMR (400 MHz, CD3OD) δ 7.22-7.26 (m, 1H), 7.05-7.09 (m, 2H), 6.73-6.78 (m, 2H), 5.17 (s, 2H), 2.84 (t, J=7.2 Hz, 2H), 2.59 (t, J=7.8 Hz, 2H), 2.44 (s, 3H). Mass spectrum (ESI, m/z): Calcd. for C21H15F6NO3S, 476.1 (M+H). found 476.1.
