39093-93-1, 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 suspension of 2?fluoro?5?nitrobenzaldehyde (2 g, 11.83mmol), thiomorpholine 1,1?dioxide (1.599 g, 11.83 mmol)and potassium carbonate (2.452 g, 17.74 mmol) inanhydrous DMF (10 mL) was heated to 50 ¡ãC under anitrogen atmosphere overnight. The reaction mixture was allowed to cool to room temperature, diluted with water (70 mL) and stirred at room temperature for 15 minutes. The precipitated solid was isolated by filtration, washed with water, slurried in 1M HC1 solution (50 mL), isolatedby filtration, sucked dry and freeze?dried overnight to give the title compound as a yellow solid (2.68 g, 80percent) ?H NMR (300 MHz, DMSO?d6) : 5 10.11 (s, 1H), 8.54 (d, 1H), 8.34 (dd, 1H), 7.43 (d, 1H), 3.69?3.80 (m, 4H), 3.36?3.45 (m, 4H) . LCMS (Method C) : = 0.95 mi m/z = 285 [M+H].
According to the analysis of related databases, 39093-93-1, the application of this compound in the production field has become more and more popular.
