Versuchsvorschrift
2-Acetamidoanthracene was prepared in 97% yield by stirring a solution of 1 equivalent of 2-aminoanthracene and 1.5 equivalents of acetic anhydride in dry tetrahydrofuran for 3 hours at room temperature. This product (2.9 g) was dissolved in 35 ml of carbon disulfide and 4 ml of oxalyl chloride was added. The stirred mixture was cooled to 0° C. and treated with 2.5 g of anhydrous aluminum chloride. Another 35 ml of carbon disulfide and 2.5 g of aluminum chloride were added after 2 hours. The mixture was stirred 2 hours at 0° C. and overnight at room temperature and then treated with dilute HCl. The brown precipitate that formed was washed with water and then digested well with 5% NaOH solution. After collection, the insoluble solids were washed with water and dried in air to give 1.25 g (35%) of a mixture of 2-,6-, and 7-acetamido-1,9-oxalylanthracenes.
