Versuchsvorschrift

200 mg (0.951 mmol) 3-(3-fluoro-oxetan-3-yl)-benzoic acid methyl ester was dissolved in 10 mL MeOH and treated with 0.40 mL 4 M aqueous NaOH solution at RT over the weekend. 0.20 mL 4 M aqueous NaOH solution was added and the mixture was stirred at 50° C. for 2 h. The reaction mixture was concentrated, acidified with 4 M aqueous hydrochlorid acid and stirred for 30 min at 0° C. The precipitate was filtered off, washed with water and dried.
