Benzofuran-5-carbonyl chloride (1 g, 5.54 mmol) in dry DCM (40 ml) is treated with N,O-dimethylhydroxylamine.HCl (0.594 g, 6.09 mmol) followed by triethylamine (1.930 ml, 13.84 mmol). After stirring at RT overnight, the mixture is diluted with DCM and washed with H2O, 1M HCl, 1M NaOH, brine, dried (MgSO4) and evaporated down to give a brown oil which is used without further purification; MS: m/z 206.1 [M+H]+
