Reaction Steps

3-Amino-1-(3-bromo-4,5-dimethoxy-phenyl)-9-chloro-1H-4-oxa-10-aza-phenanthrene-2-carbonitrile (34) (47 mg, 0.1 mmol) and triethylamine (14 μl, 0.1 mmol) and methylamine (2M in MeOH, 75 μl, 0.15 mmol) were taken in dry NMP (2 ml) and stirred at 80° C. till the reaction was complete. The reaction mixture was diluted with water to about 7 ml, stirred at room temperature for 2 h, precipitates were collected by filtration, washed with water. The residue was then purified on HPLC (high pressure liquid chromatography) (21 mm×250 mm, RP18, 5 mm) with a methanol/water gradient (5% MeOH to MeOH in 25 min, flow 21 ml/min) to pure title compound (36 mg, 77%).
