Procedure

A mixture of the appropriate chloro-substrate (1 equiv), potassium carbonate (3.0 equiv), 2-difluoromethoxy-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-benzamide (1.1 equiv) and tetrakis(triphenylphosphine) palladium0 (0.05 equiv) in acetonitrile/water (0.1 M of chloro-substrate) was stirred at 100° C. for 2 hours. Upon completion the reaction mixture was partitioned between water and CH2Cl2 and extracted with CH2Cl2. Combined organic phases were washed with brine, dried (MgSO4), filtered and concentrated in vacuo. The crude residue was purified by preparative HPLC to give the desired product.
