0.5 g of 3,4-diethoxy-phenylacetic acid are placed in 10 ml of acetic acid p.a. and 0.5 ml of 659 nitric acid are added dropwise, so that the internal temperature does not rise above 15° C. The mixture is then heated to 40° C. for 0.5 hours. After this time the solution is poured onto ice water and the precipitate formed is suction filtered.
