The precursor to Example #C.1, tert-butyl (1-(2-(4-sulfamoylphenylamino)furo[3,2-d]pyrimidin-4-yl)piperidin-4-yl)methylcarbamate, was prepared as shown in Scheme B. 2,4-Dichlorofuro[3,2-d]pyrimidine [Ark Pharm] and tert-butyl piperidin-4-ylmethylcarbamate [Astatech] are reacted following conditions given in General Procedure A to give tert-butyl (1-(2-chlorofuro[3,2-d]pyrimidin-4-yl)piperidin-4-yl)methylcarbamate. The intermediate is then reacted with 4-aminobenzenesulfonamide using the conditions described in General Procedure B to give the precursor to Example #C.1. The reaction sequence detailed above is translated in the preparations and examples section to “prepared using A from 2,4-dichlorofuro[3,2-d]pyrimidine [ArkPharm] with tert-butyl piperidin-4-ylmethylcarbamate [Astatech] and B with 4-aminobenzenesulfonamide.”
