Reaction Steps

4-Chloro-6-morpholino-quinazoline (382 mg, 1.53 mmol) and 6-chloroindoline (258 mg, 1.63 mmol) were heated at reflux in 8 mL of 1,2-dichloroethane and pyridine (264 mg, 3.36 mmol) for 16 hours. The reaction mixture was vacuum evaporated and partitioned between 100 mL of ethyl acetate and 50 mL of 5% sodium bicarbonate. The organic layer was washed with an additional 50 mL of bicarbonate and 50 mL of brine, dried with magnesium sulfate, filtered and evaporated in vacuo to a residue. This was purified by flash chromatography on silica gel eluted with 20% acetone/methylene chloride. The pure solid isolated from the column was converted to its hydrochloride salt by dissolution in methanol containing 1.1 equivalents of anhydrous hydrogen chloride and precipitation with ether; 396 mg (65%); M.P. 277°-279° C.
