Procedure

Methyl 4-((2-methyl-1H-indol-1-yl)methyl)benzoate 3 (0.500 g, 1.90 mmol) and dimethylformiminium chloride (0.200 g, 2.15 mmol) were heated to reflux in a solution of DCM (5 mL) and DMF (2 mL) for 20 h. The reaction was then cooled to RT and DCM (50 mL) was added along with sat. NaHCO3 (20 mL). The organic fraction was isolated and the aqueous solution was further extracted with DCM (2×20 mL). The combined organic fractions were washed with H2O (20 mL), brine (20 mL), dried with Na2SO4 and concentrated in vacuo. The desired product was purified via automated column chromatography method 2 (0.221 g, 37%). 1H NMR (400 MHz, CDCl3): δ 7.94 (d, J=8.1 Hz, 2H), 7.69 (m, 1H), 7.14 (m, 3H), 7.02 (d, J=8.0 Hz, 2H), 5.38 (s, 2H), 3.90 (s, 3H), 3.62 (s, 2H), 2.35 (s, 3H), 2.30 (s, 6H).
