To a solution of 4-1 (13 mg, 0.052 mmol) in DCM (0.25 mL) was added copper (II) acetate, biphenyl-3-ylboronic acid (30 mg, 0.16 mmol) and triethylamine (0.022 mL, 16 mg, 0.16 mmol) at room temperature. After 4 days, the crude mixture was diluted in DCM (4 mL), filtered, concentrated and purified via reverse phase chromatography (1-100% Acetonitrile, 0.1% TFA in H2O) and the desired fractions were concentrated to give 76-1. MS (M+H)+: observed=403.0, calculated=403.2.
