As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 39093-93-1, name is Thiomorpholine 1,1-dioxide. This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. 39093-93-1

Preparation 14 4-(4-bromobenzyl)thiomorpholine 1,1-dioxide A mixture of thiomorpholine 1,1-dioxide (270 mg, 2.0 mmol) in DMF (10 ml) was prepared at room temperature and sodium hydride (60 wt percent in oil, 96 mg, 2.40 mmol) added in one portion and the mixture stirred at room temperature for 1 h. 1-Bromo-4-(bromomethyl)benzene was then added in one portion and the mixture stirred overnight for 17.5 h under argon. The mixture was then quenched with saturated aqueous ammonium chloride solution (10 ml) and diluted with ethyl acetate (30 ml). The mixture was partitioned and the aqueous layer removed. The organic layers were then washed with 5percent aqueous lithium chloride solution (2*10 ml), brine (10 ml), dried over magnesium sulphate and the solvent removed under reduced pressure. The crude product was then purified by column (0-5percent methanol/dichloromethane) to afford 4-(4-bromobenzyl)thiomorpholine 1,1-dioxide as a colourless solid (283 mg, 0.93 mmol, 47percent). 1H NMR (500 MHz; CDCl3) delta 2.98 (brs, 4H), 3.06 (brs, 4H), 3.60 (s, 2H), 7.20 (d, 2H, J=8.1 Hz), 7.47 (d, 2H, J=8.3 Hz) ppm. Purity by LCMS (UV Chromatogram, 190-450 nm) 95percent, rt=5.0 min, m/z 306 (M+H)+

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant. 39093-93-1, we look forward to future research findings about .
