Procedure

A suspension of 2-chloro-7-fluoroquinoline-3-carbaldehyde (200 mg, 0.95 mmol), N-(cyclohexylmethyl)-N-ethylamine (140 mg, 0.99 mmol) and potassium carbonate (140 mg, 1.0 mmol) in toluene (3 mL) is stirred and refluxed for 14 hours. The reaction mixture is cooled to room temperature and then diluted with water and ethyl acetate. The organic layer is washed with 1N HCl, brine, dried over magnesium sulfate, filtered and concentrated. The crude product is purified by silica gel column chromatography to give 2-[N-(cyclohexylmethyl)-N-ethylamino]-7-fluoroquinoline-3-carbaldehyde.
