Potassium Carbonate → HCID 57831397, compound

Participants

Reaction Steps

A solution of 1.70 g (3.38 mmol, 75% pure) of methyl 4-{7-cyano-3-[2-(2-hydroxyphenyl)vinyl]heptyl}benzoate from Example 95A in 20 ml of dry acetonitrile is mixed with 1.53 g (7.76 mmol) of 4-(tert-butyl)benzyl bromide and 1.4 g (10.13 mmol) of anhydrous potassium carbonate and heated to reflux for 12 hours. The mixture is then filtered and the filtrate is concentrated to dryness. The resulting crude product is taken up on silica gel and purified by flash chromatography (mobile phase: cyclohexane/ethyl acetate 10:1). 1700 mg (3.12 mmol, 96% purity, 92% yield) of an oil are obtained.
