Participants

Reaction Steps

A reaction of a mixture comprising 130 mg of 2,6-dichloro-4-(3,4-methylenedioxybenzyl)aminoquinoline, 500 μl of ethyl isonipecotate and 1 ml of N-methyl-2-pyrrolidone was conducted on an oil bath at 150° C. for 3 hours. The reaction mixture was cooled, followed by the addition of water. The resulting mixture was extracted with ethyl acetate and the ethyl acetate layer was washed with water and a saturated aqueous solution of sodium chloride, dried over anhydrous magnesium sulfate and concentrated. The residue was purified by silica gel column chromatography with 20 to 50% ethyl acetate/hexane to give 150 mg of the title compound.
