Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 98-64-6, name is 4-Chlorobenzenesulfonamide, A new synthetic method of this compound is introduced below., name: 4-Chlorobenzenesulfonamide
General procedure: The synthesis route of compounds 1-24 followed the general pathway outlined in Scheme 1. The substituted nicotinic acid (1 mmol) mixed with benzenesulfonamide (1 mmol) through by using 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC*HCl) (1.2 mmol) and 4-dimethylaminopyridine (DMAP) (1.2 mmol) in anhydrous CH2Cl2 for 6-8 h at 70-80 °C. The reaction was monitored by TLC. The products are extracted with ethyl acetate. The extract is washed successively with 1 N HCl, water, 1 M NaHCO3, and water, dried over MgSO4, filtered and evaporated. The residue is purified by column chromatography using petroleum ether and ethyl acetate (1:1).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
