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
Step 1: 2-bromo-5-iodopyridine (1.24 g, 4.35 mmol), thiomorpholine-1,1-dioxide (882 mg, 6.53 mmol) and NaOtBu (1 .04 g, 10.87 mmol) were charged to a screw cap tube, dry toluene (25 mL) was added and the mixture was degassed by nitrogen bubbling for 5 mm. Then XantPhos (250 mg, 0.44 mmol) and Pd2(dba)3 (200 mg, 0.22 mmol) were incorporated and the tube was closed under nitrogen atmosphere. The reaction mixture was stirred at rt for 4 days. EtOAc and water were added. The phases were separated. The organic layer was dried over Mg504, filtered and the solution was concentrated to dryness. The crude material was absorbed on silica gel and purified by column chromatography eluting with CH2CI2 and a gradient of CH2CI2/MeOH from [100:0] to [95:5]. The product fractions were combined and concentrated to dryness to afford 4-(6-bromopyridin-3-yl)-1-thiomorpholine-1 ,1-dione Ex.36a (730 mg, 57percent) as yellow solid.
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.
