Related Products of 102-49-8,Some common heterocyclic compound, 102-49-8, name is 3,4-Dichlorobenzylamine, molecular formula is C7H7Cl2N, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A solution of acid 4 (0.09 g, 0.47 mmol) in dry DMF (2 mL) treated sequentially with amine (5a?i, 6a?e and 7a?h; 0.517 mmol)and triethylamine (0.94 mmol) was stirred under a N2 atmosphere for 15 min, later TBTU (0.56 mmol) was added and reaction mixture refluxed for 4?10 h. The reaction mixture was quenched with aq satd NH4Cl solution (10 mL). After 10 min, it was diluted withCHCl3 (2 10 mL) and washed with water (10 mL), NaHCO3 solution(10 mL) and brine (10 mL). The organic layers were dried over anhydrous sodium sulfate, evaporated and the residue purified by column chromatography using 30percent ethyl acetate in pet. ether to afford corresponding amides 8a?i, 9a?e and 10a?h.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3,4-Dichlorobenzylamine, its application will become more common.
