Temperature	70 °C

Reaction Steps

A mixture of 2,4-dichloro-7-tosyl-7H-pyrrolo[2,3-d]pyrimidine (171 mg, 0.500 mmol), 4-amino-1-N-Boc-piperidine (100 mg, 0.500 mmol) and TEA (0.150 mL, 1.08 mmol) in dioxane (4 mL) was stirred at 70° C. for 20 h. Water and EtOAc were added. The organic phase was separated, washed with 1N HCl, then with 5% NaHCO3, dried over Na2SO4, concentrated in vacuo to give tert-butyl 4-(2-chloro-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)piperidine-1-carboxylate (202 mg).
