Versuchsvorschrift
A mixture of 4-(aminocarbonyl)-2-chlorophenyl 1,1-dimethylethyl carbonate (6.86 g, 0.025 mol) and 4N HCl in dioxane (50 mL) in dioxane (30 mL) was heated at reflux for 4 hr. The reaction mixture was cooled, and precipitated solid was collected by filtration affording 3-chloro-4-hydroxybenzamide as a white solid, used without further purification. LC/MS (method E) tR 0.88 min; m/z 172 (M+H).
