Procedure

A suspension of 4-hydroxy quinoline 60 was refluxed with phosphorus oxychloride for 30 minutes. To the cooled reaction mixture was added aqueous ammonia and the product was obtained by extracting with methylene chloride, dried over sodium sulfate and concentrated in vacuo. 1H NMR (CDCl3) δ (ppm): 1.44 (3H, t, J=7.14 Hz), 2.70 (3H, s), 4.50 (2H, q, J=7.14 Hz), 7.62 (1H, t, J=7.69 Hz), 7.78 (1H, dd, J=10.71, 7.69 Hz), 7.95 (2H, d, J=10.72, 8.24 Hz). m/z 286.7 (MH+).
