To a solution of 3-methyl-4-(3-((2-(trimethylsilyl)ethoxy)methyl)-3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)cyclopentanamine (0.27 g, 0.7 mmol) and DIEA (0.18 mL, 1.05 mmol) in DCM (5 mL) was added cyclopropanesulfonyl chloride (0.098 g, 0.7 mmol) drop-wise. The resulting mixture was stirred at ambient temperature for about 1 h. Another 0.18 mL of DIEA and 0.098 g of cyclopropanesulfonyl chloride were added and the reaction was continued for about 3 h. The solvent was removed and the residue was partitioned between saturated aqueous ammonium chloride and EtOAc (20 mL each). The organic layer was washed with brine (10 mL), dried over anhydrous MgSO4, filtered and concd. The residue was purified by silica gel chromatography (100% DCM for 5 min, then to 6% MeOH in DCM over next 30 min) to yield N-(3-methyl-4-(3-((2-(trimethylsilyl)ethoxy)methyl)-3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)cyclopentyl)cyclopropanesulfonamide (0.18 g, 52% yield) as an off-white solid. LC/MS (Table 1, Method a) Rt=2.45 min; MS m/z 490 (M+H)+.
