5-(2-Chlorophenyl)-1-(2,6-dichlorophenyl)-3,4-dihydro-7-hydroxy-7-methoxy-2(1H)-quinolinone was prepared from 5-bromo-1-(2,6-dichlorophenyl)-3,4-dihydro-7-methoxy-2(1H)-quinolinone (INTERMEDIATE 1) and 2-chlorophenylboronic acid by a procedure analogous to that described in INTERMEDIATE 2. Mass spectrum (ESI) 434.0 (M+1). 1H NMR (500 MHz, CDCl3): δ 7.43-7.54 (m, 2H); 7.30-7.42 (m, 4H) 6.48 (d, J=2.5 Hz, 1H); 5.82 (d, J=2.5 Hz, 1H); 5.89 (d, J=2.5 Hz, 1H); 3.69 (s, 3H); 2.63-2.88 (m, 4H).
