Adding a certain compound to certain chemical reactions, such as: 98-64-6, name is 4-Chlorobenzenesulfonamide, belongs to amides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 98-64-6, HPLC of Formula: C6H6ClNO2S
General procedure: To a round-bottom flask (500 mL) that contained a solution of aryl sulfonamide (6 mmol), 4-dimethyaminopyridine (DMAP, 13 mmol), and 1-[3-(dimethyamino)-propyl]-3-ethylcarbodiimide hydrochloride (EDCI, 13 mmol) in CH2Cl2 (150 mL) was added the synthesized cinnamic acid (6 mmol) at room temperature. The resulting mixture was stirred at room temperature for 12 h, then cooled to 5 °C, and acidified to pH 1 with addition of HCl aqueous solution (10percent), which was followed by extraction with CH2Cl2/MeOH (9:1, 3 .x. 100 mL). The combined organic layers were washed with H2O and brine, dried over Na2SO4, and concentrated in vacuo. The residue was subjected to silica gel chromatography or crystallization if necessary to afford the compounds (9a-16e) (Scheme 1).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Chlorobenzenesulfonamide, other downstream synthetic routes, hurry up and to see.
