실험 절차

7 g (60% purity, 21.519 mmol) 3-methoxy-4-nitro-benzamidine are dissolved in methanol and combined with 11 ml (44 mmol) 4 N dioxanic hydrochloric acid, the solvents are eliminated in vacuo. The residue and 6.13 g (44.384 mmol) potassium carbonate are suspended in 350 ml acetonitrile and combined with 3.24 ml (22.764 mmol) ethyl 4-chloracetoacetate and 880 mg (5.301 mmol) potassium iodide. The reaction mixture is stirred for 16 h at 45° C. The reaction mixture is diluted with water and combined with 1 N sodium hydroxide solution, and extracted with ethyl acetate. The aqueous phase is adjusted to pH 1 with 1 N HCL and saturated with sodium chloride. The product is then suction filtered.
