Reaktionsschritte
To a solution of methyl 3-chloro-4-(1,3-difluoropropan-2-yloxy)benzoate (2.00 g, 7.56 mmol) in dioxane (15.11 mL) was added LiOH (1.0 M aq, 22.67 mL, 22.67 mmol). The reaction was stirred at 30° C. for 1.5 h in a 1 L round-bottomed flask. The reaction was cooled to room temperature and poured into 1 N HCl. A precipitate was formed and filtered by vacuum filtration to give the title compound (1.5 g) as a white solid. LCMS m/z=250.9 [M+H]+.
