Reaction Conditions:
with sulfuryl dichloride at 20; for 1 h;Cooling with ice;
Steps:
7.B Preparation of 5-chloro-2-methoxy-4-toluenesulfonyl chloride
In a 250 mL three-necked flask was added 1-chloro-4-methoxy-2-methylbenzene (18.7 g, 119.4 mmol)Under ice-cooling, sulfuryl chloride (27.8 g, 238.9 mmol) was slowly added dropwise and reacted at room temperature for 1 h. After completion of the reaction, the reaction solution was poured into ice water and analyzed.A large amount of solid, suction filter, filter cake vacuum drying, in 5-chloro-2-methoxy-4-toluenesulfonyl chloride 23.1g, the yield of 75.6%.
