Procedure

To a solution of N-((1S,3R,4S)-3-ethyl-4-(5-nitro-1H-pyrrolo[2,3-b]pyridin-4-ylamino)cyclopentyl)cyclopropanesulfonamide (0.123 g, 0.314 mmol) in DMF (3.0 mL) at about 0° C. was added NaH (60% in mineral oil, 0.015 g, 0.37 mmol). The reaction mixture was stirred for about 5 min. 4-Methylbenzene-1-sulfonyl chloride (0.060 g, 0.314 mmol) was added and the reaction mixture was stirred for about 30 min. Additional NaH (60% in mineral oil, 0.007 g, 0.18 mmol) was added and the reaction mixture was stirred for about 10 min. Additional NaH (60% in mineral oil, 0.005 g, 0.12 mmol) was added and the reaction mixture was stirred for about 15 min. Additional 4-methylbenzene-1-sulfonyl chloride (0.012 g, 0.063 mmol) was added and the reaction mixture was stirred for about 40 min. The reaction mixture was concd under reduced pressure. The residue was dissolved in EtOAc (25 mL) and washed with water (15 mL). The organic layer was separated, dried over anhydrous MgSO4, filtered and concd under reduced pressure to give N-((1S,3R,4S)-3-ethyl-4-(5-nitro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-4-ylamino)cyclopentyl)-cyclopropanesulfonamide (0.218 g) as a red-orange oil containing 40 mol % DMF and 1 equivalent EtOAc: LC/MS (Table 1, Method n) Rt=0.88 min; MS m/z 548 (M+H)+.
