Reaction Steps

Following a procedure similar to that described in Example 128, ethyl 6-chloro-7-[(4-chlorophenyl)thio]-2-(trifluoromethyl)-2H-1-benzopyran-3-carboxylate (Example 192) was treated with OXONE® yielding the products labeled Example 193 and Example 194: mp 213.8-217.4° C. 1H NMR (acetone-d6/300 MHz) 7.91 (s, 1H), 7.83 (d, 2H, J=8.7 Hz), 7.62 (m, 4H), 5.98 (q, 1H, J=6.8 Hz). 19F NMR (acetone-d6/282 MHz) −79.3 (d, J=7.2 Hz) ESLRMS m/z 435 (M−H). ESHRMS m/z 434.9470 (M−H, Calc'd 434.9472). Anal. Calc'd for C17H9Cl2F3O4S: C, 46.70; H, 2.07; Cl, 16.22; S, 7.33. Found: C, 46.80; H, 2.28; Cl, 16.75; S, 7.39.
