With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.84468-15-5,Isoquinoline-5-sulfonyl chloride,as a common compound, the synthetic route is as follows.

The powdered aryl or heteroaryl sulphonyl chloride (ARYL-SOACI) (1 mmol) was added in small portions to a cooled flask (0 C) containing the ethylene diamine (10 mmol) in dry dichloromethane (20 ml) with vigorous stirring. The reaction was then stirred for 3 hours at room temperature under a nitrogen atmosphere. After checking its conclusion by TLC, the reaction mixture was extracted with 10% aqueous hydrochloric acid solution. After separation of the two resulting phases, the pH of the aqueous layer was adjusted to 10 with a 10% aqueous sodium hydroxide solution and the aqueous layer was extracted with dichloromethane. The organic layer was then dried (anhydrous magnesium sulphate), filtered and evaporated under reduced pressure to give the aryl-sulphonamido-alkylamine as a solid. The aryl or heteroaryl sulphonyl chlorides used in the procedure described above were either obtained from commercial sources or were prepared through reaction of the respective sulphonic acids (2.3 mmol) with thionyl chloride (2.2 ml) in the presence of dimethylformamide (0.3 ml). The reaction was carried out under reflux for 2 hours and, after cooling to room temperature, the reaction mixture was evaporated under reduced pressure to give a solid sulphonyl chloride which was used immediately in the next step., 84468-15-5

The synthetic route of 84468-15-5 has been constantly updated, and we look forward to future research findings.
