Versuchsvorschrift

Methyl 3-benzyloxy-6-methoxy-picolinate (20 mg) was dissolved in 1 ml of methanol. A 1 N aqueous sodium hydroxide solution (0.33 ml) was added to the solution, and a reaction was allowed to proceed at room temperature for 3 hr. The reaction solution was then adjusted to pH 3 by the addition of 1 N hydrochloric acid. The precipitate was collected by filtration to give 12 mg (yield 63%) of the title compound.
