实验过程

To a round-bottom flask equipped with a stirbar is added phenol 3H (R=pentyl) (5 g), (4-(4-Methyl-3-pentenyl)-1-cyclohexenyl)carboxylic acid (R=n-pentyl) (3.3 g), dicyclohexylcarbodiimide (5.11 g), dimethylaminopyridine (202 mg), and anhydrous tetrahydrofuran (50 mL). The reaction is stirred overnight, at which time the solution is poured into water and extracted with 1:1 hexanes:ethyl acetate. The combined organic layers are washed with brine and dried over potassium carbonate, and the solution is concentrated in vacuo. Filtration through silica gel using 10% ethyl acetate in hexanes gives the pure product.
