Reaction Conditions:
with sodium hydroxide in tetrahydrofuran at 20; for 12 h;
Steps:
1.1 (1) Synthesis of Compound a
Nonaethylene glycol(1 g, 2.4 mmol, 1 eq, Leap Labchem)And 5N sodium hydroxide (0.72 ml, 3.6 mmol, 0.75 eq) in a round flask,Tetrahydrofuran 12 mlP-Toluenesulfonyl chloride (0.342 mg, 1.8 mmol, 0.75 eq, TCI)It was slowly added at room temperature and stirred for 12 hours.Then, after extracting with dichloromethane and distilled water,The dichloromethane layer was dehydrated with magnesium sulfate and filtered to obtain transparent liquid particles through distillation under reduced pressure (0.941 g, 69%).
