Procedure
5′-(6-methyl-biphenyl-3-yl-carbamoyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-carboxylic acid ethyl ester was prepared from 5′-(3-iodo-4-methyl-phenylcarbamoyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4 carboxylic acid ethyl ester and phenylboronic acid following a method similar to the one described in the synthesis of 5′-(2-methyl-biphenyl-4-ylcarbamoyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-carboxylic acid ethyl ester above. The product was isolated after silica gel column purification with 20-50% EtOAc in hexanes gradient. HRMS m/z calcd for C27H29N3O3 [M+H]+: 444.2282. Found: 444.2282
