Participants

Reaction Steps

5′-(2′-Methoxy-6-methyl-biphenyl-3-ylcarbamoyl)-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 2-methoxylphenyl boronic 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 20-40% EtOAc in hexanes gradient. HRMS m/z calcd for C28H31N3O4 [M+H]+: 474.2388. Found: 474.2387.
