Procedure

The precursor to Example #H.1.1, 3-chloro-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)benzenesulfonamide, was prepared as shown in Scheme B. 2-Hydrazinyl-5-tosyl-5H-pyrrolo[2,3-b]pyrazine (Preparation #9) and 4-(tert-butoxycarbonylamino)bicyclo-[2.2.2]octane-1-carboxylic acid are reacted following the conditions given in General Procedure A to give tert-butyl 4-(2-(5-tosyl-5H-pyrrolo[2,3-b]pyrazin-2-yl)hydrazinecarbonyl)bicyclo[2.2.2]octan-1-ylcarbamate. This hydrazide is cyclized using the conditions given in General Procedure C to afford tert-butyl 4-(6-tosyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyrazin-1-yl)bicyclo[2.2.2]octan-1-ylcarbamate. This carbamate is deprotected using General Procedure I to yield 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. This amine is sulfonylated using the conditions described in General Procedure N to give the precursor to Example #H.1.1. The reaction sequence detailed above is translated in the preparations and examples section to “using A from Preparation #9 and 4-(tert-butoxycarbonylamino)bicyclo-[2.2.2]octane-1-carboxylic acid [Prime Organics], C with TEA, I, N from 3-chlorobenzenesulfonyl chloride”.
