Analyzing the synthesis route of 39093-93-1

39093-93-1 Thiomorpholine 1,1-dioxide 6484228, aThiomorpholine compound, is more and more widely used in various.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.39093-93-1,Thiomorpholine 1,1-dioxide,as a common compound, the synthetic route is as follows.

Step 1. In a 25 mL round-bottomed flask, 6-bromo-1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridine (420 mg, 1.19 mmol, Eq: 1.00) and thiomorpholine 1,1-dioxide (482 mg, 3.57 mmol) were combined with toluene (3 ml) to give a yellow solution. Bis(tri-tert-butylphosphine)palladium(0) (60.7 mg, 119 mumol) and sodium tert-butoxide (400 mg, 4.16 mmol, Eq: 3.5) were added. The reaction mixture was heated to 80¡ã C. and stirred for 1 h. The reaction mixture was poured into 20 mL sat NaCl and extracted with EtOAc (3.x.20 mL). The organic layers were dried over MgSO4 and concentrated in vacuo. The crude material was purified by flash chromatography (silica gel, 40 g, 20percent to 40percent EtOAc in hexanes) to give 6-(1,1-Dioxo-1lambda*6*-thiomorpholin-4-yl)-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridine (327 mg, 68percent) as a yellow oil that solidified as off white solid upon standing.
