Reaction Conditions

Reaction Steps

A round bottom flask was charged with a magnetic stir bar, N4-[5-(methylthio)pentyl]quinoline-3,4-diamine (3.17 g, 11.46 mmol) and anhydrous pyridine (46 mL) under a nitrogen atmosphere. The resulting homogeneous solution was cooled to 0° C. in an ice-water bath. To the cooled solution was added neat heptanoyl chloride (1.87 g, 12.61 mmol). The reaction was judged to be complete after stirring at ambient temperature for 1 hour. The volatiles were removed under reduced pressure and the resulting oil was partitioned between chloroform and water. The layers were separated. The organic layer was washed with saturated aqueous sodium bicarbonate and brine, dried over anhydrous sodium sulfate, filtered and then concentrated under reduced pressure to afford N-(4-{[5-(methylthio)pentyl]amino}quinolin-3-yl)heptanamide (4.44 g, 11.46 mmol) which was isolated as a brown oil and used without further purification.
