Versuchsvorschrift
Into a 50 mL round bottom flask was placed 5-phenyl-6-(4-(2-(pyrrolidin-1-yl)ethoxy)phenyl)furo[2,3-d]pyrimidin-4 (3H)-one 46 (132 mg, 0.329 mmol), and benzene (40 mL). The flask was equipped with a magnetic stir bar, dean-stark trap and a reflux condenser. The reaction was brought to reflux with some of the solvent having been distilled into the dean-stark trap. The reaction was allowed to cool to room temperature and phosphorous oxychloride (300 mg, 1.96 mmol) was added dropwise. The reaction was heated at reflux for 20 hours.
