実験手順

Activated molecular sieves (6.0 g) 4 Å were placed in an oven dried flask and cooled to room temperature under nitrogen. To the flask was charged with N-methoxy-N-methyl-1H-indole-2-carboxamide (0.45 g, 2.2 mmol), (3-fluorophenyl)boronic acid (0.94 g, 6.7 mmol), cupric acetate (0.60 g, 3.3 mmol), and methylene chloride (80 mL) and then pyridine (0.72 mL, 8.9 mmol). The reaction mixture was stirred at room temperature over weekend, then filtered through a pad of Celite. The filtrate was concentrated and purified on silica gel (eluting with 0-25% EtOAc in hexane) to give the title compound (0.30 g, 46%). LCMS calculated for C17H16FN2O2(M+H)+: m/z=299.1. Found: 299.0.
