Example 4 Synthesis of 2-(2,6-Dichlorophenylamino)-1,6,7-trimethyl-1,8-dihydro-imidazo[4,5-h]isoquinoline-9-one. A solution of 2,6-dichloro-3-nitrobenzonitrile (98.7 g, 0.455 mol) in EtOAc (910 mL) was cooled to 5 C. 40% Aqueous methylamine (79.5 mL, 1.14 mol) was added with vigorous mechanical stirring, keeping the temperature at 10-15 C. After addition was complete, stirring was continued for 3 h at the same temperature. More methylamine (16 mL, 0.23 mol) was added, and the mixture stirred for a further 1.5 h at room temperature. Water (300 mL) was added, followed by hexane (450 mL). The mixture was stirred for 15 min, filtered, and the solid washed with water and MeOH, to give 6-chloro-2-methylamino-3-nitrobenzonitrile (80.3 g, 83%), mp 167-170 C.
