4943-86-6, name is 2-Amino-N-(4-chlorophenyl)benzamide, belongs to amides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. COA of Formula: C13H11ClN2O
General procedure: A flask was charged with 2-aminobenzamide (1a; 27.2 mg, 0.2 mmol), pentane-2,4-dione (2A;30.0 mg, 0.3 mmol), FeCl3¡¤6H2O (10.8 mg, 0.04 mmol), and PEG-400/H2O (1.0 mL, 1:9 (v/v)).The reaction was stirred at 100 C for 24 h. When the reaction was complete monitored by TLC,the mixture was cooled to room temperature, extracted with EtOAc (3¡Á20 mL). The combined organic phase was washed with water, dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography to give the product 3aA (29.3 mg, 91%) as white solid.
The synthetic route of 4943-86-6 has been constantly updated, and we look forward to future research findings.
