HCID 18511631N-[3,5-Dichloro-4-(6-chloro-benzothiazol-2-yloxy)-phenyl]-4-trifluoromethoxy-benzenesulfonamide

Procedure

N-[3,5-Dichloro-4-(6-chlorobenzothiazol-2-yloxy)-phenyl]-4-trifluoromethoxy-benzenesulfonamide was synthesized (83%) from 3,5-dichloro-4-(6-chloro-benzothiazol-2-yloxy)-phenylamine (420) and 4-trifluoromethoxybenzenesulfonyl chloride (Maybridge) in a similar manner as described in Examples 70-91. 1H NMR (400 MHz, DMSO-d6) δ 11.16 (s, 1H), 8.15 (d, J=2.2 Hz, 1H), 8.03-7.98 (m, 2H), 7.68 (d, J=8.7 Hz, 1H), 7.65 (d, J=8.2 Hz, 2H), 7.46 (dd, J=8.7, 2.2 Hz, 1H), 7.31 (s, 2H). MS (EI): m/z 567 (M−H).
