A mixture of 2-({2-chloro-7-[(4-methylphenyl)sulfonyl]-7H-pyrrolo[2,3-d]pyrimidin-4-yl}amino)-6-fluorobenzamide (0.20 g, 0.44 mmol), 1-acetyl-6-(methyloxy)-1,2,3,4-tetrahydro-7-quinolinamine (0.10 g mg, 0.43 mmol) was dissolved in 2,2,2-trifluoroethanol (10 mL) and hydrochloric acid (1.0 mL, 4.0 mmol, 4M in 1,4-dioxane) was added. The mixture was heated at 90° C. in a sealed tube for 24 h. The reaction was cooled, excess saturated aqueous sodium bicarbonate was added, and extracted with dichloromethane. The organic layer was separated, dried over magnesium sulfate, filtered, concentrated, diluted with tetrahydrofuran (35 mL) and treated with excess 27% aqueous ammonia (20 mL). The reaction was stirred in a sealed tube at 80° C. for 1 h, cooled, and the layers were separated. The organic layer was dried over sodium sulfate, concentrated, and purified by flash silica gel column chromatography (0 to 20% methanol /dichloromethane). “Pure” fractions were isolated, concentrated, dissolved in 1,4-dioxane (7.0 mL), treated with potassium hydroxide (4.0 mL, 20 mmol, 5M in water) and stirred for 24 h at 80° C. The reaction was cooled; the organic layer was separated, dried over sodium sulfate, and purified by flash silica gel column chromatography. Further purification via reverse phase HPLC (5 to 90% acetonitrile/water, 0.05% trifluoroacetic acid) provided 2-[(2-{[1-acetyl-6-(methyloxy)-1,2,3,4-tetrahydro-7-quinolinyl]amino}-1H-pyrrolo[2,3-d]pyrimidin-4-yl)amino]-6-fluorobenzamide (0.03 g, 91% pure, 0.054 mmol, 13% over 3 steps). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.81-1.91 (m, 2 H), 2.15 (s, 3 H), 2.68 (m, 2 H), 3.68 (t, J=6.1 Hz, 2 H), 3.86 (s, 3 H), 6.27 (s, 1 H), 6.85 (m, 1 H), 6.91-6.98 (m, 1 H), 7.02 (m, 1 H), 7.40-7.47 (m, 1 H), 7.52 (s, 1 H), 8.02 (bs, 1 H), 8.08 (bs, 1 H), 8.36-8.41 (m, 1 H), 8.46 (s, 1 H), 10.43 (s, 1 H), 11.44 (bs, 1H); ESIMS (M+H)+=490.
