Procedure
4-[4-(3-Cyano-propylsulfamoyl)-4,7-diaza-spiro[2.5]oct-7-yl]-pyrrolo[2,3-d]pyrimidine-7-carboxylic acid tert-butyl ester (intermediate 18) was dissolved in CH3CN (0.4 mL), added Cs2CO3 and (3-bromo-propyl)-benzene. Stirred at for 16 h and then added additional (3-bromo-propyl)-benzene (2 equivalents) before being stirred at rt for 3 days. The crude reaction mixture was filtered through a syringe filter (0.45 μm) and purified by standard preparative HPLC purification. The residual oil was dissolved in THF (1 mL), added TFA (0.5 mL) and then stirred at rt for 2 h. The crude reaction mixture was concentrated in vacuo and redissolved in MeOH (0.5 mL). The pure compound was obtained by standard preparative HPLC purification of the reaction mixture.
