Versuchsvorschrift
In a 2-liter three-necked flask cooled with ice, 135 ml of ice water was placed, and 490 ml of concentrated sulfuric acid was gradually added to the ice water with stirring to prepare a sulfuric acid solution. Subsequently, 150 g of iron(III) chloride was added to the sulfuric acid solution at room temperature, and after reaction of 1 hour, 30 g of 1,2-dimethoxybenzene was further added to prepare a reaction mixture. After reaction of 3 hours, the reaction mixture was cooled with ice, and 1 liter of ice water was gradually added to the reaction mixture. After stirring of 1 hour, the reaction mixture was filtered through a glass filter to obtain crude crystals of the above compound (a) of 13 g (yield: 43%).
