Yield:81311-96-8 110 g
Reaction Conditions:
with dichloro sulfoxide in dichloromethane;N,N-dimethyl-formamide at 25; for 2 h;
Steps:
3 Example 3:
SM-2 (88g) was suspended in DCM (1L), and stirred at 25°C until uniform.N,N-dimethylformamide (2g) was added, thionyl chloride (113g) was added dropwise,During the dropwise addition, the gas was released, and the reaction was kept at 25 °C. After 2 h,The system was gradually dissolved and clear, the outgassing was stopped, and the external temperature of the reaction solution was concentrated at 40 °C to obtain the product,It is a khaki solid, a total of 110g,The yield is calculated as 100%, and it is directly cast into the next step.
