YieldReaction ConditionsOperation in experiment
With potassium hydroxide; In methanol; water; for 3h;Reflux; General procedure: The 5-aryl-3-amino-2-carboxylic acid methyl ester (16.6 mmol) was added to a solution of KOH (60 mL, 0.6 M inH2O) and MeOH (60 mL). The mixture was heated to reflux for 3 h,concentrated, and washed with EtOAc (2 50 mL). The aqueous layer was cooled with ice and acidified by addition of a saturated aqueous solution of KHSO4. The precipitated solid was collected by filtration, washed with H2O (2 30 mL) and dried under reduced pressure over CaCl2.
