Reaktionsschritte
To dimethyl 5-hydroxyisophthalate (4.0 g, 19.03 mmol, 1.00 equiv) in THF (10 mL) was added lithium hydroxide (20 mL, 2M in water) and the resulting solution was stirred overnight at 40° C. The mixture concentrated under vacuum to remove the organic solvents and then the pH of the solution was adjusted to ˜2 with 6N hydrochloric acid. The resulting solids were collected by filtration and dried in a vacuum oven to afford 2.0 g (58%) of 5-hydroxyisophthalic acid as a white solid.
