Participants

Reaction Steps

To a solution of 2.06 g of 5-(4'-ethoxycarbonyloxy-3'-methoxyphenyl)pentadienoic acid (E,E)-farnesylamide in 40 ml of methanol is added 20 ml of 2N aqueous solution of sodium hydroxide. The mixture is stirred at room temperature for one hour. The reaction mixture, after acidified with 1N hydrochloric acid, is extracted with chloroform. The organic layer is washed with water and dried over sodium sulfate. The solvent is distilled off under reduced pressure, and the residue is subjected to column chromatography on silica gel. From the fraction eluted with chloroform is obtained 1.67 g of 5-(4'-hydroxy3'-methoxyphenyl)pentadienoic acid (E,E)-farnesylamide (13). Spectroscopic data of the product support the structure of the formula (13) below.
