1H NMR (DMSO-d6): δ15.0 (bs, 2H), 9.25 (s, 1H), 8.18 (s, 1H), 7.98 (d, J=8.4 Hz, 2H), 7.77 (d, J=9.0 Hz, 2H), 7.29 (d, J=8.7 Hz, 2H), 7.21 (d, J=8.7 Hz, 2H); mp 230-232° C. The intermediate 1-[4-(4-trifluoromethylphenoxy)phenyl]ethanone was prepared from 4-hydroxyacetophenone and 4-fluorobenzotrifluoride using the method described for the synthesis of 1-[4-(4-fluorophenoxy)phenyl]ethanone.
