Reaction Steps

To a solution of 2-bromo-3-chlorobenzoic acid methyl ester (3.86 mmol) in 4 mL DMF was added CuCN (4.24 mmol) and the reaction mixture was heated to 90° C. overnight. After cooling to 10° C., 10 mL EtOAc and 3 mL 1M NaOH solution were added and stirring was continued at RT for 30 min. The aq. phase was separated and extracted twice with EtOAc. The combined organic layers were washed with brine, dried over MgSO4 and concentrated in vacuo. Purification by preparative LC-MS (method L) gives the desired product as white solid.
