Versuchsvorschrift

49 mg (1.13 mmol) of sodium hydride (as a 55% w/w suspension in mineral oil) were washed twice, each time with hexane, and were suspended in 6 ml of dimethylformamide. 2 ml of a dimethylformamide solution Containing 289 m9 (0.97 mmol) of 5-diethoxyphosphoryl-1-(4-oxopentyl)benzene were added to the suspension, whilst ice-cooling. The reaction mixture was then immediately allowed to return to room temperature, after which it was stirred for 30 minutes. 300 mg (0.808 mmol) of N-(2-ethyl-6-formylphenyl)-2-(9H-xanthen-9-yl)acetamide were then added to the reaction mixture, once again whilst ice-cooling. The mixture was then stirred for 1 hour at the ice-cooling temperature and then for 3 hours at room temperature. At the end of this time, the reaction solution was poured into ice-water and extracted with diethyl ether. The organic extract was washed with water. The solvent was removed by distillation under reduced pressure, and the resulting residue was recrystallized from a mixture of methylene chloride and diethyl ether, to give 220 mg (yield 53%) of the title compound as crystals, melting at 168°-170° C.
