Versuchsvorschrift
To a solution of 2-bromo-4-methyl-5-nitrobenzonitrile (500 mg, 2.07 mmol) in ethanol (20 mL) was added tin chloride (785 mg, 4.14 mmol). The mixture was refluxed for 5 h. After cooling to room temperature, triethylamine (1.01 g, 10 mmol) was added. The mixture was concentrated and purified by silica chromatography (30-50% ethyl acetate in hexanes gradient) to afford 5-Amino-2-bromo-4-methylbenzonitrile a as beige solid; ESMS m/z 211 (M+H+).
