Reaction Steps

A solution of 2,4-dichloro-7-tosyl-7H-pyrrolo[2,3-d]pyrimidine (275 mg, 0.804 mmol), 1-methyl-indazol-5-ylamine (118 mg, 0.803 mmol) and DIEA (0.350 mL, 2.01 mmol) in dioxane (7 mL) was stirred at 110° C. for 20 h. EtOAc and H2O were added. The organic phase was separated, washed with 1N HCl, then with 5% NaHCO3, dried over Na2SO4, concentrated in vacuo to give 2-chloro-N-(1-methyl-1H-indazol-5-yl)-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (316 mg).
