Related Products of 111-46-6 ,Some common heterocyclic compound, 111-46-6, molecular formula is C4H10O3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
Synthesis of 2-(2-hydroxyethoxy)ethyl 4-methylbenzenesulfonate (Compound A3)Into a 2000-mL 3 -necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen was placed a solution of 2-(2 -hydroxy ethoxy)ethan-l-ol (A2, 42.4 g, 399.55 mmol, 1.00 equiv) in dichloromethane (1000 mL) and triethylamine (27.9 g, 275.72 mmol, 0.25 equiv). To the above was added p-toluenesulfonyl chloride (19.1 g, 100.18 mmol, 0.50 equiv). After stirring for 1 h at 25C, the resulting mixture was washed with 1×500 mL of aq. potassium hydrosulfate (1M) and 1×500 mL of aq. sodium bicarbonate (5%) respectively. The organic layer was dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column and eluted with dichloromethane/methanol (100: 1). This resulted in Compound A3 as an oil.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,111-46-6, its application will become more common.
