Thiomorpholine 1,1-dioxide, A common heterocyclic compound, 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., 39093-93-1
A solution of 1-(bromomethyl)-3-nitrobenzene (2.400 g, 11.110 mmol), thiomorpholine 1,1-dioxide (1.427 g, 10.554 mmol) and N,N-diisopropylethylamine (2.5 16 mL, 14.442 mmol) in acetonitrile (16 mL) was stirred at the room temperature for 24 hr. Then, water was added to the reaction mixture, followed by extraction with dichloromethane. The organic layer was washed with aqueous saturated sodium chloride solution, dried with anhydrous MgSO4, filtered, and concentrated in vacuo. The residue was chromatographed (Si02, 12 g cartridge; ethyl acetate / hexane = 0 percent to 50 percent) to give 4-(3-nitrobenzyl)thiomorpholine 1,1-dioxide as yellow solid (2.800 g, 93.2 percent).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 39093-93-1. We look forward to the emergence of more reaction modes in the future.
