Participants

Reaction Steps

A solution of 1-(4-{2-[7-(3-chloro-propoxy)-quinazolin-4-ylamino]-ethyl}-phenyl)-3-phenyl-urea (20 mg, 0.042 mmol) and dimethylamine (94.7 mg, 0.840 mmol) in DMF (1 mL) was heated at 150° C. in CEM microwave for 10 min. The reaction mixture was purified using silica gel preparative thin layer chromatography to provide the title compound (10 mg, 49%). 1H-NMR (400 MHz, DMSO-d6): δ 8.69 (s, 1H), 8.66 (s, 1H), 8.41 (s, 1H), 8.19 (t, 1H, NH), 8.10-8.12 (m, 1H), 7.43-7.45 (m, 2H), 7.36-7.38 (m, 2H), 7.26 (t, 2H), 7.17 (d, J=8.8 Hz, 2H), 7.08-7.11 (m, 1H), 7.05 (d, J=2.4 Hz, 1H), 6.95 (t, 1H), 4.13 (t, 2H), 3.69 (q, 2H), 2.89 (t, 2H), 2.44 (t, 2H), 2.20 (s, 6H), 1.89-1.93 (m, 2H). LC-MS (ESI) m/z 485.3 (M+1).
