Procedure

Dissolved 1.00 g (3.20 mmol) 6-amino-4-[(3-chloro-4-fluorophenyl)amino]-3-quinolinecarbonitrile in 2 ml hot DMF, added 12 ml THF and chilled to 0° C. under N2. Added 490 μl (3.52 mmol) triethyl amine and 295 μl (3.52 mmol) acryloyl chloride. Removed ice bath at 15 minutes, and at 1.5 hours stripped solvent. Slurried residue with a dilute sodium bicarbonate, collected solids, and washed with water. Recrystallized from ethyl acetate, giving 215 mg of yellow solid: mass spectrum (electrospray m/e): M+H=367.1, 369.1.
