Participants

Reaction Steps

Aluminum trichloride (2.7 g, 20.0 mmol) and methylene chloride (30 mL) were combined under an atmosphere of nitrogen and 5-bromo-7-azaindole (67, 400.0 mg, 2.30 mmol) in methylene dichloride (20 mL) was added. The reaction was stirred at room temperature for 70 minutes. 4-Methoxybenzoic acid chloride (0.38 g, 2.2 mmol) (prepared from the corresponding carboxylic acid using the protocol described in Example 1, Scheme 13, Step 4) in methylene dichloride (7.0 mL) was added. The reaction was stirred at room temperature for 2 hours, then poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, and concentrated to give the compound (116, 250 mg, 34%).
