Versuchsvorschrift

20 g of methyl 3-hydroxy-benzo[b]thiophene-2-carboximidate (Example 1) are heated under reflux in 500 ml of isopropanol for three days. The methanol being formed is constantly distilled off by passing through a stream of nitrogen. Evaporation to dryness and recrystallization of the residue from ethyl acetate yields yellow crystals with an m.p. of 208° C.
