200 mg | With iron; ammonium chloride In ethanol; water for 2 h; Reflux | General procedure: To a solution of N-(4,4-difluorocyclohexyl)-8-nitroquinazolin-4-amine (90 mg, 0.292 mmol) in EtOH (2 mL) were added iron powder (163 mg, 2.92 mmol) and NH4Cl (127 mg, 2.33 mmol) and the reaction mixture was heated at reflux for 2 h. Then the reaction mixture was filtered through celite. The celite bed was washed with 10percent MeOH in CHCl3. The filtrate was washed with a saturated aq. NaHCO3 solution and water. The organic layer was separated, dried, filtered and concentrated to afford 70 mg of the title product. 1H NMR (300 MHz, DMSO d6): δ 8.38 (s, 1H), 7.64 (d, J=7.2 Hz, 1H), 7.35 (d, J=7.8 Hz, 1H), 7.19-7.14 (t, J=7.8 Hz, 1H), 6.87 (d, J=7.8 Hz, 1H), 5.71 (s, 2H), 4.38 (m, 1H), 2.09-1.97 (m, 6H), 1.73-1.69 (m, 2H); MS (m/z): 279.12 (M+H)+.The title compound was prepared following the procedure described in step-2, Intermediate-9 using 4-chloro-8-nitroquinoline (Intermediate-11, step-2, 250 mg, 1.20 mmol), NH4Cl (513 mg, 9.60 mmol) and iron powder (671 mg, 12.0 mmol) in EtOH (6 mL) and water (3 mL) to afford 200 mg of the title product. 1H NMR (400 MHz, CDCl3): δ 8.69 ((d, J=4.6 Hz, 1H), 7.55-7.53 (d, J=8.4 Hz, 1H), 7.48 (d, J=4.6 Hz, 1H), 7.46-7.42 (t, J=7.6 Hz, 1H), 7.00-6.98 (d, J=7.6 Hz, 1H), 5.06 (br s, 2H); MS [M+H]+: 179.25. |
