Procedure

A mixture of tert-butyl 4-(2-chloro-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)piperidine-1-carboxylate (202 mg, 0.400 mmol), 4-aminobenzamide (82 mg, 0.60 mmol) and trimethylsilyl chloride (0.200 mL, 1.58 mmol) in nBuOH (4 mL) was stirred at 116° C. in a sealed tube for 20 h. It was concentrated in vacuo. The residue was purified by HPLC to give 4-(4-(piperidin-4-ylamino)-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)benzamide (58 mg).
