실험 절차

5′-(3-tert-Butyl-phenylcarbamoyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-carboxylic acid ethyl ester was prepared from N-(3-tert-butyl-phenyl)-6-chloro-nicotinamide and ethyl isonipecotate following a procedure similar to the one described in the synthesis of 5′-(3-iodo-4-methyl-phenylcarbamoyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4 carboxylic acid ethyl ester above. The product was isolated by silica gel column purification with 20-30% EtOAc in hexanes gradient. FIRMS m/z calcd for C24H31N3O3 [M+H]+: 410.2438. Found: 410.2436
