Reaction Steps

4-[(3,4-Dichloro-2-fluorophenyl)amino]-6-(methyloxy)quinazolin-7-ol hydrochloride (469 mg, 1.20 mmol) was dissolved in dimethylformamide (1 mL) and potassium carbonate (828 mg, 6.00 mmol) was added followed by octahydro-2H-quinolizin-3-ylmethyl methanesulfonate (466 mg, 1.89 mmol) in dimethylformamide (1 mL). The mixture was stirred at 70° C. for 38 h and then was partitioned between ethyl acetate and water. The aqueous portion was extracted with ethyl acetate. The combined organic portion was dried over sodium sulfate, filtered and concentrated in vacuo to afford a brown oil which was purified by column chromatography (15-20% methanol in dichloromethane). The purified material was crystallized from methanol to afford N-(3,4-dichloro-2-fluorophenyl)-6-(methyloxy)-7-[(octahydro-2H-quinolizin-3-ylmethyl)oxy]quinazolin-4-amine as a cream colored solid (83.4 mg, 0.165 mmol, 14% yield). 1H NMR (400 MHz, CDCl3): 8.69 (s, 1H), 8.53 (t, 1H), 7.34 (dd, 1H), 7.28-7.22 (m, 1H), 7.23 (s, 1H), 6.98 (s, 1H), 4.06-3.95 (m, 2H), 4.02 (s, 3H), 3.09 (d, 1H), 2.87 (d, 1H), 2.43-2.27 (m, 1H), 2.10-1.97 (m, 1H), 1.95-1.84 (m, 2H), 1.80-1.52 (m, 5H), 1.46-0.95 (m, 5H); MS (EI) for C25H27N4O2FCl2: 505 (MH+).
