To an oven dried flask that cooled under argon was added the (1H-indol-3-yl)methanol (1.0 grams, 6.8 mmol, 0.1M in dry dichloromethane, purchased from Fisher Scientific, stored over 4 angstrom molecular sieves) and DMAP (0.083 grams, 0.68 mmol). While stirring at 0° C., triethyl amine (2.0 mL, 14.3 mmol, purchased from Fisher Scientific) was added followed by benzoyl chloride (0.96 mL, 8.2 mmol, purchased from Fisher Scientific). Once the reaction was complete it was diluted with water, and the organic layer removed. The aqueous layer was then washed with dichloromethane twice and the organic material combined. The organic material was dried with sodium sulfate, filtered, and concentrated. Purification using a Teledyne ISCO on silica support (hexanes/ethyl acetate gradient) afforded the desired 1-benzoyl-1H-indol-3-yl)methyl benzoate. 42% yield. 1H-NMR δ8.42 (d, 1H), 8.02 (dd, 2H), 7.76 (m, 3H), 7.62 (dd, 1H), 7.54 (m, 3H), 7.47-7.37 (m, 5H), 5.50 (s, 2H).
