Reaction Steps

To a mixture of 4′,6-dichloro-4-methoxy-[1,1′-biphenyl]-3-carboxylic acid (309 mg, 1.04 mmol), EDCI (272 mg, 1.43 mmol), HOBt (195 mg, 1.43 mmol), Et3N (288 mg, 2.85 mmol) in dichloromethane (10 mL) at 0° C., piperazine-2-carbonitrile was added at 0° C. and the resulting mixture was stirred at RT for 8 h. The mixture was partitioned between dichloromethane and water. The organic layer was washed brine, dried over MgSO4, filtered and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (dichloromethane/methanol=50:1) to afford the desired product (225 mg, 61% yield). ESI-MS m/z: 444.3[M+H]+.
