Synthetic Route of 53531-69-4, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 53531-69-4, name is (4-Bromophenyl)methanesulfonyl chloride belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
General procedure: Various alkyl halides 23a-k (2.5 mmol) and thiourea (0.19 g, 2.5 mmol) were refluxed together in EtOH (2.5 mL) for 1 h. Afterr emoval of EtOH at reduced pressure, the obtained solid was slowly added to a mixture of NCS (1.33 g, 10 mmol), 2 M HCl (0.68 mL) and MeCN (4 mL) over 15 min. Upon completion of the reaction (TLC monitoring), the solvent was removed under vacuum. Then H2O(5 mL)was added to the residue and stirred for 15 min, the resulting solid was filtered and dried under an infrared lamp to afford the corresponding sulfonyl chlorides 24a-k. Without further purification, 24a-k was added in portions to a solution of NaN3 (195 mg ,3 mmol) in acetone/H2O (10 mL, acetone/H2O = 1:1) at 0 C. After being stirred at room temperature for 4 h, the reaction mixtur ewas concentrated in vacuo and H2O (10 mL) was added to the residue. The aqueous solution was extracted with CHCl3 (3 x 10 mL). The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure to afford sulfonyl azides 25a-k.
The synthetic route of (4-Bromophenyl)methanesulfonyl chloride has been constantly updated, and we look forward to future research findings.
