実験手順
The title compound was prepared according to the procedure described in Example 1 starting following Step 5 and 6 coupling (3-(3-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 (300 MHz, CD3OD) δ 7.34-7.52 (m, 3H), 6.83-6.91 (m, 2H), 5.21 (s, 2H), 2.88 (t, J=7.5 Hz, 2H), 2.61 (t, J=7.2 Hz, 2H), 2.368 (s, 3H). Mass spectrum (ESI, m/z): Calcd. for C21H15F6NO3S, 474.1 (M−H). found 474.1.
