Procedure

To a vial containing methyl 1H-indole-3-carboxylate (402 mg, 2.297 mmol), pyridin-4-ylboronic acid (847 mg, 6.89 mmol), copper (II) acetate (542 mg, 2.99 mmol), 4 {acute over (Å)} molecular sieves (4 g) and 1,10-phenanthroline (828 mg, 4.59 mmol) were added DCM (9 ml) and triethylamine (0.320 ml, 2.297 mmol). The mixture was stirred at RT for 4 days then filtered through a pad of Celite (washed with MeOH). Evaporation and purification by HPLC (after dilution with DMF and filtration) afforded the title compound as a yellow solid.
