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
Preparation 75 4-(3-Methoxy-4-nitrobenzyl)thiomorpholine-1,1-dioxide Thiomorpholine 1,1-dioxide (0.242 g, 1.788 mmol) and triethylamine (0.19 mL, 1.341 mmol) were added to a solution of 4-(bromomethyl)-2-methoxy-1-nitrobenzene (Preparation 74, 0.22 g, 0.894 mmol) in THF (2.2 mL). The reaction mixture was stirred overnight at room temperature before being concentrated under reduced pressure and purified via Biotage silica gel column chromatography eluting with (DCM/EtOAc 99/1 to 90/10) to afford the title product as a white solid (242 mg, 90percent). 1H NMR (500 MHz, CDCl3): delta 3.00-3.04 (m, 4H), 3.09-3.12 (m, 4H), 3.71 (s, 2H), 3.98 (s, 3H), 7.01 (m, 1H), 7.09 (m, 1H), 7.84 (d, J=8.2 Hz, 1H). LC (Method C)-MS (ESI, m/z) tR 2.03 min, 301 [(M+H+), 100percent].
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.
