Participants

Reaction Steps

Treat a solution of methyl 5-(tert-butoxycarbonylaminomethyl)-2-(difluoromethyl)benzoate (1.43 g, 4.54 mmol, 1.0 equiv) in 1,4-dioxane (20 mL) with sodium hydroxide (5 N aqueous, 1.81 mL, 9.07 mmol, 2.0 equiv), and stir the mixture at room temperature overnight. Concentrate under reduced pressure, and adjust the pH to 4 with aqueous HCl. Extract with EtOAc (2×40 mL), and wash the combined organic extracts with saturated aqueous NaCl, separate, and dry the organic phase over Na2SO4, filter, and concentrate under reduced pressure to give the title compound (1.21 g, 88%). MS (m/z) 319 (M+18).
