Procedure

A mixture of 2-chloro-4-(cyclopropylamino)-7-tosyl-7H-pyrrolo[2,3-d]pyrimidine-5-carbonitrile (150 mg, 0.387 mmol), 4-aminobenzenesulfonamide (103 mg, 0.599 mmol) and trimethylsilyl chloride (0.200 mL, 1.58 mmol) in nBuOH (4 mL) was stirred at 135° C. for 20 h. It was concentrated in vacuo. The residue was purified by HPLC to give the titled compound (45 mg). MS 370.3 (M+H); UV 202.8, 254.6, 305.0 nm.
