[0200] Add 3-methoxy-4-hydroxyacetophenone (600g, 3.61moL) and anhydrous potassium carbonate (698g, 5.055moL) into DMF (5v / w, 2500mL), and stir well at 25°C for 30min , and then 1,3-bromochloropropane (795.9g, 1.4moL) was slowly added dropwise, and after the dropwise addition was completed, the reaction was stirred at 25°C for 10h. After the reaction, filter with suction, wash the filter cake with a small amount of DMF, collect the filtrate, slowly pour the filtrate into ice water and stir vigorously, a solid is precipitated, filter with suction, and dry the filter cake to obtain 827.2 g of a solid, with a yield of 93.8%.
