実験手順

A solution of 200 mg (0.346 mmol) N-(3,5-bis-trifluoromethyl-benzyl)-6-iodo-N-methyl-4-o-tolyl-nicotinamide (Example 4) and 84 mg (0.69 mmol) 3-hydroxybenzonitrile in 4 ml pyridine was deoxygenated by three freeze-thaw cycles. After addition of 5 mg (0.04 mmol) copper(I) oxide and 96 mg (0.69 mmol) potassium carbonate under a stream of argon the reaction mixture was heated at reflux for 70 h. Cooling to room temperature was followed by dilution with tert-butyl methyl ether and washing with two portions of 1 M aqueous hydrochloric acid solution. The combined aqueous layers were extracted with tert-butyl methyl ether. The combined organic layers were washed with saturated aqueous sodium carbonate solution and brine, dried with sodium sulfate and concentrated. Column chromatography afforded 174 mg (88%) of the title compound as a light brown solid.
