Reaction Steps

100 mg (0.278 mmol) of 1-acetyl-6-bromo-2-methyl-4-phenylamino-1,2,3,4-tetrahydroquinoline), 36 mg (0.31 mmol) of zinc cyanide, and 18 mg (0.015 mmol) of tetrakis(triphenylphosphine)palladium(0) were added to 1.5 mL of DMF, and the mixture was stirred for 2 hours at 120° C. under an argon atmosphere. After completion of the reaction, water was added to the reaction liquid, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dehydrated over anhydrous sodium sulfate, and then concentrated under reduced pressure. The resulting residue (104 mg) was purified by using silica gel preparatory thin layer chromatography (ether:hexane=5:1), and thus 63 mg (cis:trans=3:1, 74.1%) of the title compound was obtained as a colorless amorphous solid.
