Procedure

Example 1 was repeated to react 67 g (0.32 mol) of E-4-bromo-1-phenyl-1-butene with 29 g of potassium carbonate (0.21 mol) and 51.9 g of N-hydroxyphthalimide (0.32 mol) in 320 ml of N-methylpyrrolidone. The crude product, precipitated by means of ice-water, was taken up in dichloromethane and washed twice with dilute sodium hydroxide solution. A customary working up gives the product in a 56% yield.
