Reaction Steps

4-(2-Methyl-propane-2-sulfonylaminocarbonyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-5′-carboxylic acid (3-iodo-4-methyl-phenyl)-amide was prepared from 5′-(3-Iodo-4-methyl-phenylcarbamoyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-carboxylic acid and t-butyl sulfonamide in a manner similar to the one described in the synthesis of 4-(2-Methyl-propane-2-sulfonylaminocarbonyl)-3,4,5,6-tetrahydro-2H-[1,4]bipyridinyl-5′-carboxylic acid (4-iodo-3-methyl-phenyl)-amide. The product was isolated after a silica gel column purification with 2-5% MeOH in CH2Cl2. HRMS m/z calcd for C23H29N4O4SI [M+H]+: 585.1027. Found: 585.1027.
