Reaction Steps

To a solution of 5-{[1-(N,N-dimethylglycyl)-5-(methyloxy)-2,3-dihydro-1H-indol-6-yl]amino}-8,10-difluoro-3-[(4-methylphenyl)sulfonyl]pyrrolo[2′,3′:4,5]pyrimido[6,1-b]quinazolin-7(3H)-one (300 mg, 0.445 mmol) in THF (5 mL) was added [(4-fluorophenyl)methyl]amine (1.01 mL, 8.89 mmol). The resulting mixture was let stir at rt for 16 h at which time it was diluted with ethyl acetate and washed with a saturated ammonium chloride solution, a saturated sodium bicarbonate solution, water and a saturated brine solution. Organics were dried over sodium sulfate and solvents removed under reduced pressure and purified via SiO2. This lead to a yellow solid containing 2-({2-{[1-(N,N-dimethylglycyl)-5-(methyloxy)-2,3-dihydro-1H-indol-6-yl]amino}-7-[(4-methylphenyl)sulfonyl]-7H-pyrrolo[2,3-d]pyrimidin-4-yl}amino)-4,6-difluoro-N-[(4-fluorophenyl)methyl]benzamide. This crude material was dissolved in 1,4-dioxane (5 mL) and transferred to a 20 ml microwave vessel. A solution of 2 M NaOH (5 ml) was added and reaction heated in microwave at 120° C. for 8 minutes. Resulting brown solution was diluted with ethyl acetate and washed with a 10% ammonium chloride solution, saturated sodium bicarbonate solution, water and a saturated brine solution. Organics were dried over sodium sulfate and solvents removed under reduced pressure to afford a yellow solid which was purified via chromatography on SiO2 to afford 2-[(2-{[1-(N,N-dimethylglycyl)-5-(methyloxy)-2,3-dihydro-1H-indol-6-yl]amino}-1H-pyrrolo[2,3-d]pyrimidin-4-yl)amino]-4,6-difluoro-N-[(4-fluorophenyl)methyl]benzamide (67 mg, 0.104 mmol) as an off white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 2.23 (s, 6 H), 3.06-3.18 (m, 4 H), 3.76 (s, 3 H), 4.16 (t, J=8.29 Hz, 2 H), 4.51 (d, J=5.86 Hz, 2 H), 6.17 (d, J=1.19 Hz, 1 H), 6.81-7.01 (m, 3 H), 7.13 (t, J=8.84 Hz, 2 H), 7.38 (dd, J=8.29, 5.72 Hz, 2 H), 7.78 (s, 1 H), 8.43 (d, J=11.90 Hz, 1 H), 8.51 (s, 1 H), 9.14-9.25 (m, 1 H), 10.38 (s, 1 H), 11.32 (br. s., 1 H).
