Reaktionsschritte
A mixture of 5 grams (24 mmol) of 4-(trifluoromethoxy)benzoyl fluoride, 1.87 grams (29 mmol) of sodium azide, 0.2 grams of 18-Crown-6 ether, and 20 ml. of acetonitrile was stirred at room temperature for two hours under an atmosphere of dry nitrogen. The reaction mixture was diluted with diethyl ether, filtered and concentrated under reduced pressure, with a bath temperature of 40° C., to give the title compound as a turbid oil. IR showed adsorptions at 2280, 2240 and 1695 cm-1.
