Participants

Reaction Steps

A mixture of 5-(methyloxy)-1-[(4-methylphenyl)sulfonyl]-2,3-dihydro-1H-indol-6-amine (4.0 g, 12.5 mmol), 2-({2-chloro-7-[(4-methylphenyl)sulfonyl]-7H-pyrrolo[2,3-d]pyrimidin-4-yl}amino)-6-fluorobenzamide (8.6 g, 18.79 mmol) and a 4 N solution of HCl in dioxane (16 mL, 62.5 mmol) in 2,2,2-trifluoroethanol (250 mL) was heated overnight in a sealed vessel at 80° C. The reaction mixture was diluted with a saturated NaHCO3 solution, and the resulting slurry was filtered and the solids were taken up into THF (1L). The resulting slurry was filtered and the filtrate was concentrated. The resulting orange solid was dissolved in THF (250 mL), and a 27% aqueous NH4OH solution (250 mL) was added and the reaction mixture was stirred overnight. The organic volatiles were evaporated, and the residue was extracted with CH2Cl2 (3×200 mL). The organic layers were combined, dried (Na2SO4), concentrated onto Celite and purified by silica gel chromatography using 0-2%THF/CH2Cl2 to obtain 2-fluoro-6-({2-({5-(methyloxy)-1-[(4-methylphenyl)sulfonyl]-2,3-dihydro-1H-indol-6-yl}amino)-7-[(4-methylphenyl)sulfonyl]-7H-pyrrolo[2,3-d]pyrimidin-4-yl}amino)benzamide as a yellow solid (2.8 g, 30% for 2 steps). ESIMS (M+H)+=742.17.
