Potassium Carbonate → Ethyl (7E)-6-[2-(4-cyanophenyl)ethyl]-8-{2-[(5-phenylpentyl)oxy]phenyl}oct-7-enoate

Participants

Reaction Steps

A solution of 127 mg (0.32 mmol) of ethyl (7E)-6-[2-(4-cyanophenyl)ethyl]-8-(2-hydroxyphenyl)oct-7-enoate in 10 ml of acetonitrile is mixed with 88.42 mg (0.39 mmol) of (5-bromopentyl)benzene and 67.25 mg (0.49 mmol) of potassium carbonate and stirred under reflux for 12 hours. After cooling, the mixture is concentrated. The residue is taken up in ethyl acetate and extracted with water. The organic phase is washed with saturated sodium chloride solution, dried over sodium sulfate and concentrated. The resulting residue is purified by preparative HPLC. 128 mg (0.24 mmol, 73.4% of theory) of the title compound are obtained.
