4-Methoxy-2-methyl-1H-indole (805 mg, 5 mmol) was added to a mixture of 160 mg (4 mmol) of 60% sodium hydride/mineral oil (washed with hexane before adding DMF) in 10 mL of DMF and after stirring for 0.67 hours, 782 mg (4 mmol) of α,2,6-trichlorotoluene was added. The mixture was stirred at room temperature for 5 hours, diluted with water and extracted with ethyl acetate. The ethyl acetate solution was washed with brine, dried (MgSO4) and after concentrating at reduced pressure, the residue was chromatographed on silica gel eluting with 20% EtOAc/hexane to give 1.08 g (84% yield) of 1-[(2,6-dichlorophenyl)methyl]-4-methoxy-2-methyl-1H-indole, melting at 154-157° C.
