実験手順

A solution of NaNO2 (0.29 g, 4.2 mmol) in water (1.6 mL) was added dropwise to a solution of 5-amino-2-bromobenzoic acid (0.86 g, 4 mmol) in HCl 2N (6 mL) and water (6 mL) at 0° C. during 15 minutes. The reaction mixture was stirred for 20 minutes and then added dropwise to a solution of CuCN (0.7 g, 8 mmol) and NaCN (0.4 g, 8 mmol) in water (5 mL) at 60° C.; the mixture was heated at 60° C. for further 15 minutes. After cooling at room temperature HCl (2N) was added and the product was extracted twice with AcOEt; the combined organic layers were dried and evaporated to give the title compound as a brown solid. Yield (0.6 g, 67%).
