Reaction Steps

5-(2-Chlorophenyl)-3,4-dihydro-7-methoxy-1-(3-methoxycarbonyl-6-methylphenyl)-2(1H)-quinolinone was prepared from 5-bromo-3,4-dihydro-7-methoxy-1-(3-methoxycarbonyl-6-methylphenyl)-2(1H)-quinolinone (INTERMEDIATE 16) and 2-chlorophenylboronic acid by a procedure analogous to that described in INTERMEDIATE 2.
