Versuchsvorschrift
A solution of 3.00 g (10.8 mmol) of methyl 4-amino-3-iodobenzoate and 1.30 g (54.1 mmol) of lithium hydroxide in 150 ml of a dioxane/water mixture (1:1) was stirred at room temperature for 6 h. The dioxane was distilled off in vacuo, and the remaining aqueous phase was adjusted to pH 5 with 1 M hydrochloric acid. The precipitate was filtered off with suction and washed with water. 2.80 g (98%) of the title compound were obtained as a solid.
