実験手順

3,3,3-Trifluoropropane-1-sulfonyl chloride (0.194 g, 0.987 mmol, Matrix) was added dropwise to a solution of TEA (0.31 mL, 2.2 mmol) and 3-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-4-methylcyclopentanamine (0.28 g, 1.1 mmol, Preparation #53) in DMF (10 mL). The resulting mixture was stirred at ambient temperature for about 144 h. The solvent was removed under reduced pressure and the residue was partitioned between EtOAc and water (20 mL each). The layers are separated and the organic layer was washed with brine (30 mL), dried over anhydrous MgSO4, filtered, and concd under reduced pressure. The residue was purified by using General Procedure AA (Table 2, Method 9, Rt=17.7 min, or =negative) to give N-((1S,3S,4R)-3-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-4-methylcyclopentyl)-3,3,3-trifluoropropane-1-sulfonamide (0.021 g, 4.6%) as a white solid: LC/MS (Table 1, Method a) Rt=1.79 min; MS m/z 416 (M+H)+.
