Procedure

Phenyl N-(4-Chloro-3-(pyrid-3-yl)phenyl)carbamate (D67) (0.12 g, 0.00037 mole) in dry dimethylformamide (6 ml) was treated under argon, with 5-methoxy-6-trifluoromethylindoline (D11) (0.08 g, 0.00037 mole) and heated to 120° C. for 2 hours. After cooling to ambient temperature, the solvent was removed in vacuo. The residue was partitioned between 1N aqueous sodium hydroxide solution and dichloromethane. The organic layer was dried (Na2SO4) and evaporated in vacuo. The residue was triturated in diethyl ether, filtered and dried in vacuo at 60° C. to afford the title compound (0.06 g, 36%) as a grey-green solid (mp 210-213° C.)
