Versuchsvorschrift
A mixture of N-(2-carbamoyl-4-propoxy-phenyl)-nicotinamide (980 mg, 3.27 mmol) in EtOH (20 mL) was treated with NaOH (654 mg, 16.37 mmol). The resulting mixture was stirred at room temperature for 18 h. After the reaction was completed, the volatiles were removed in vacuo. The residue was partitioned between H2O (50 mL) and ethyl acetate (50 mL). The aqueous layer was neutralized to pH 7 by slowly adding aq. citric acid and then a precipitate formed. The precipitate was collected and dried to give 1.00 g of iv-a as a grey solid (quantitative yield). LCMS m/z=282.1 (M+1) (Method B) (retention time=1.60 min).
