Versuchsvorschrift
To 1000 ml. of cold, stirring NH4OH, 63 g. (0.26 mole) of 5-(p-chlorophenyl)-2-furoyl chloride is added portionwise. The resulting mixture is stirred at ice bath temperature for 15 minutes and then is stored at room temperature for 18 hours. The solid is filtered, is washed with water and is dried at 60° to yield 56 g. (97%).
