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

A mixture of 143 (0.558 g; 2.54 mmol), thiomorpholine-l, l-dioxide (0.516 g; 3.82 mmol), EDCI (0.585 g; 3.05 mmol) and HOBT (0.344 g; 2.54 mmol) in methylene chloride (10 ml) was stirred at room temperature under argon atmosphere for 24 hours. The crude mixture was dissolved in ethyl acetate and washed with a 2 N [NAOH] solution. The organic layer was dried on magnesium sulphate, evaporated and purified by flash chromatography eluting with a gradient [5-10percent] of 3.5 N NH3 in MeOH/methylene chloride to give 144 as an oil.
