Versuchsvorschrift
The title compound was prepared according to the procedure described in Example 1 starting from (3-(4-ethylphenyl)-5-(trifluoromethyl)isothiazol-4-yl)methyl methanesulfonate following Step 5 and 6 using ethyl 3-(4-hydroxynaphthalen-1-yl)propanoate as coupling agent to afford the desired product as an off-white solid. 1H-NMR (300 MHz, CDCl3) δ 8.22 (d, J=8.1 Hz, 2H), 7.98 (d, J=8.4 Hz, 2H), 7.63 (d, J=8.4 Hz, 2H), 7.58 (t, J=7.5 Hz, 1H), 7.46 (t, J=7.5 Hz, 1H), 7.22 (d, J=8.1 Hz, 3H), 6.77 (d, J=7.8 Hz, 1H), 5.22 (s, 2H), 3.39 (t, J=7.8 Hz, 2H), 2.82 (t, J=8.1 Hz, 2H), 2.65 (q, J1=15.5 Hz, J2=7.5 Hz, 2H), 1.20 (t, J=7.8 Hz, 3H). Mass spectrum (ESI, m/z): Calcd. for C26H22F3NO3S, 486.1 (M+H). found 486.1.
