実験手順

To a stirred suspension of 3,4-dimethoxy-N-methyl-5-nitro-benzamide (0.40 g, 1.66 mmol) in toluene (10 mL) was added phosphorous pentachloride (0.38 g, 1.83 mmol) portionwise. Upon completion of addition, the reaction mixture was warmed to reflux till complete disappearance of starting material. Evaporation to dryness resulted in a crude solid that was washed with diethyl ether, affording 3,4-dimethoxy-N-methyl-5-nitro-benzimidoyl chloride, 0.37 g (85%).
