YieldReaction ConditionsOperation in experiment
71% Stage #1: methyl 3,5-dimethoxybenzoate; isopropyl alcohol With sulfuric acid In water at 80℃; for 1h; Large scale; Stage #2: With water at 20 - 90℃; Large scale; 1.1 Step 1: Isopropylation Add 1kg of water to the reactor and add 7kg of concentrated sulfuric acid dropwise to the water. After the addition is complete,The reaction kettle is heated and set at 80 . After the temperature of the liquid in the kettle drops to 80 Add 1kg of 3,5-dimethoxybenzoic acid methyl ester, then dropwise add 310g of isopropanol. After the dropwise addition, react at 80 for 1h.Lower the temperature to room temperature, add 5kg of water to the reaction solution dropwise, the temperature during the dropwise addition process should not exceed 90,After the dropwise addition, the temperature is lowered to room temperature, filtered, the filter cake is washed with an appropriate amount of water, pressure filtered until no liquid drops, and dried at 85 The product was recrystallized with xylene to obtain 812g of white needle-like solid product with a yield of 71%.
