After 0.67 hours, 707 mg (4 mmol) of 1-(chloromethyl)naphthalene was added. After 5 hours, the mixture was diluted with water and extracted twice with ethyl acetate. The combined ethyl acetate was washed with brine, dried (MgSO4) and concentrated at reduced pressure. The residue was chromatographed on silica gel and eluted with 20% EtOAc/hexane to give 1.17 g (97% yield) of 4-methoxy-2-methyl-1-[(1-naphthalenyl)methyl]-1H-indole.
