Reaction Conditions

Reaction Steps

Under an argon atmosphere, 300 mg of t-butyl N-(2-fluoro-6-iodobenzyl)carbamate, 0.29 mL of cinnamyl acetate, 1.28 mL of bistributyltin, and 70 mg of PdCl2(dppf)2 were dissolved in 2.5 mL of DMF, followed by stirring at 120° C. for 2 hours. After completion of the reaction, to the reaction liquid was added diethyl ether, followed by filtration through Celite, and to the filtrate was added water, followed by extraction with diethyl ether. Then, the organic layer was washed with an aqueous sodium bicarbonate solution and saturated brine, dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The residue obtained was purified using PLC (n-hexane:ethyl acetate=3:1) to obtain 121 mg (yield 52%) of a title compound as a yellow solid.
