Versuchsvorschrift

A round bottom flask was charged with 4-(6-tosyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyrazin-1-yl)bicyclo[2.2.2]octan-1-amine (0.40 g, 0.92 mmol), TEA (0.51 mL, 3.7 mmol) in DCM (3 mL) and DMF (6 mL). Cyclopropanesulfonyl chloride (0.16 g, 1.1 mmol) was added drop-wise and the resulting suspension was stirred at ambient temperature for about 18 h. The solvent was removed under reduced pressure and DCM (10 mL) was added. The crude material was purified by silica gel chromatography eluting with a gradient of 0-10% MeOH/DCM to give N-(4-(6-tosyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyrazin-1-yl)bicyclo[2.2.2]octan-1-yl)cyclopropanesulfonamide (0.27 g, 55%): LC/MS (Table 2, Method a) Rt=2.14 min; MS m/z 541 (M+H)+.
