With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1228779-96-1,3-Nitro-4-(((tetrahydro-2H-pyran-4-yl)methyl)amino)benzenesulfonamide,as a common compound, the synthetic route is as follows.,1228779-96-1
A 3-L jacketed reactor (Kettle 1) equipped with a mechanical stirrer, nitrogen inlet/outlet, temperature control unit and reflux condenser was inerted with nitrogen and charged with 3-nitro-4-(((tetrahydro-2H-pyran-4-yl)methyl)amino)benzenesulfonamide (19.7 g, 0.95 equiv), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC, 22.1 g, 1.75 equiv), 4-dimethylaminopyridine (DMAP, 16.1 g, 2 equiv) and dichloromethane (DCM, 200 ml_, 5 vo I). In a separate 1-L reactor (Kettle 2) equipped with a mechanical stirrer, nitrogen inlet/outlet was charged with 2-((1 H-pyrrolo[2,3-b]pyridin-5-yl)oxy)-4-(4-((4′-chloro-5,5- dimethyl-3, 4, 5, 6-tetrahydro-[1 ,1 ‘-biphenyl]-2-yl)methyl)piperazin-1-yl)benzoic acid hydrochloride salt (40.0 g, 65.8 mmol), and DCM (400 mL, 10 vol). Triethylamine (36.7 mL, 4.00 equiv) was added in one portion. The solution in Kettle 2 was dosed into Kettle 1 using a transfer pump. The batch was stirred at room temperature for 5-25 h then acetic acid (10% v/v, 10 Vol, 400 mL) was added to the batch and stirred for 15 min.
As the paragraph descriping shows that 1228779-96-1 is playing an increasingly important role.
