Procedure

51.3 g (0.23 mol) of the 1-bromo-4-phenyl-2-butyne obtained above were added dropwise in the course of 30 minutes to a mixture consisting of 230 ml of N-methylpyrrolid-2-one, 3 g of potassium iodide, 37 g (0.23 mol) of N-hydroxyphthalimide and 20.6 g (0.15 mol) of potassium carbonate. Stirring was carried out for a further 5 hours at 60° C. and then overnight at room temperature, the mixture was poured into 800 ml of ice water and the precipitated crystals were filtered off under suction and washed thoroughly with water and isopropanol.
