Reaction Steps

N1-[1-(4-bromophenyl)-2-(1-pyrrolidinyl)ethyl]-N2-(3,4-dichlorophenyl)-N1,N2-dimethylglycinamide (100 mg, 0.200 mmol) was dissolved in 1.5 mL of DMF and combined with [2-(aminocarbonyl)phenyl]boronic acid (40 mg, 0.240 mmol), Pd(dppf)2Cl2 (8 mg, 0.01 mmol), and 400 uL of 2M Na2CO3 in water. The reaction mixture was heated to at 80° C. and stirred for 18 h. Ethyl acetate (4 mL) and brine (4 mL) were added and the reaction mixture was filtered. The organic layer was separated and the solvent was removed under reduced pressure. The residue was dissolved in 1.0 mL DMSO and purified by preparative HPLC (Phenomenex 75×30 mm column, 40 mL/min flow rate, A: 0.1% TFA in acetonitrile B: 0.1% TFA in water, A: 10 to 100% over 15 min, UV detection at 215 nm) to give 51 mg (47%) of the title compound as a yellow solid. MS (ES) m/e 539/541 [M+H]+.
