To a suspension of 5-chloro-8-fluoro-3-[(4-methylphenyl)sulfonyl]pyrrolo[2′,3′:4,5]pyrimido[6,1-b]quinazolin-7(3H)-one HCl salt (375 mg, 0.782 mmol) in 2,2,2-trifluoroethanol (10 mL) was added N1-[5-amino-2-methyl-4-(methyloxy)phenyl]-N2,N2-dimethylglycinamide (204 mg, 0.861 mmol). The resulting mixture was let stir at 60° C. for 45 min. Solvents were removed under reduced pressure to afford a green residue. Half of this material was dissolved in THF (10 mL) and aqueous ammonium hydroxide (27%) (30 mL, excess) was added. After stirring at rt for ˜36 h, the reaction was diluted with EtOAc and the organic layer was washed with water and a saturated brine solution and dried over sodium sulfate. Solvents were removed under reduced pressure. The residue was dissolved in dioxane (6 mL) in a microwave safe vessel and 2N NaOH (4 mL) was added. The reaction was then heated in a microwave at 120° C. for 15 min and then diluted with EtOAc. The organic layer was washed with water and a saturated brine solution and dried over sodium sulfate. Solvents were removed under reduced pressure and the residue purified by chromatography on SiO2 to afford 2-[(2-{[5-[(N,N-dimethylglycyl)amino]-4-methyl-2-(methyloxy)phenyl]amino}-1H-pyrrolo[2,3-d]pyrimidin-4-yl)amino]-6-fluorobenzamide (52 mg, 0.103 mmol) as a beige solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 2.17 (s, 3 H) 2.32 (s, 6 H) 3.03 (s, 2 H) 3.84 (s, 3H) 6.25 (dd, J=3.30, 1.65 Hz, 1 H) 6.86-6.97 (m, 2 H) 6.97-7.03 (m, 1 H) 7.40-7.49 (m, 1 H) 7.52 (s, 1 H) 8.04 (br. s., 1 H) 8.11 (s, 1 H) 8.16 (s, 1 H) 8.47 (d, J=8.42 Hz, 1 H) 9.19 (s, 1 H) 10.53 (s, 1 H) 11.37 (br. s., 1 H).
