Versuchsvorschrift

To a suspension of 2-hydrazinyl-5-tosyl-5H-pyrrolo[2,3-b]pyrazine (0.390 g, 1.287 mmol, Example #1 Step D), 4-((N,N-diethylsulfamoyl)methyl)-2-ethylcyclopentanecarboxylic acid (0.375 g, 1.287 mmol), and HATU (0.538 g, 1.416 mmol) in DCM (6.4 mL) was added TEA (0.538 mL, 3.86 mmol). The reaction mixture was stirred at ambient temperature for about 1 h. The reaction mixture was partitioned between water (50 mL) and DCM (50 mL). The aqueous layer was extracted with DCM (2×50 mL). The organic layers were combined and concd under reduced pressure. The material was purified by silica gel (120 g) chromatography eluting with a gradient of 20-100% EtOAc in DCM to provide N,N-diethyl-1-(3-ethyl-4-(2-(5-tosyl-5H-pyrrolo[2,3-b]pyrazin-2-yl)hydrazinecarbonyl)cyclopentyl)methanesulfonamide (0.730 g, 98%) as a brown solid: LC/MS (Table 1, Method b) Rt=2.39 min; MS m/z: 577 (M+H)+.
