Versuchsvorschrift

The mixture of methyl 5-formyl-3-iodobenzoate (2.5 g), malonic acid (1.8 g) and piperidine (0.2 ml) in pyridine (25 ml) was stirred for 3 hours at 100° C. The mixture was added to water and adjusted to pH 2 with 6N-hydrochloric acid. The isolated precipitate was collected by filtration to give methyl 5-[(E)-2-carboxyethenyl]-3-iodobenzoate (2.4 g)
