Versuchsvorschrift
32 g (170.04 mmol) of the compound (from example XXVIII) are dissolved in 87.1 ml (0.93 mmol) of phosphoryl chloride. 2.80 ml (22.11 mmol) of N,N-dimethylaniline are slowly added dropwise, and the mixture is stirred at 100° C. for one hour. The reaction solution is then stirred at room temperature for another two hours. The phosphoryl chloride is removed under reduced pressure using a rotary evaporator. Water/dichloromethane 9:1 is added to the residue, which is then boiled for 5 minutes. The mixture is then neutralized using saturated sodium bicarbonate solution and the product is filtered off with suction and dried under high vacuum.
