Reference of 2106-02-7,Some common heterocyclic compound, 2106-02-7, name is 2-Chloro-4-fluoroaniline, molecular formula is C6H5ClFN, 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 microwave tube was charged with 2-(9-bromo-4,5-dihydro-6-oxa-1-thia-benzo[e]azulen-2-yl)-[1,3,4]oxadiazole (0.64 g; 1.83 mmol), 2-chloro-4-fluoroaniline (0.44 ml; 3.68 mmol), TFA (0.27 ml; 3.63 mmol) and toluene (5 ml). The mixture was heated in a microwave at 160 C. for 30 min., diluted with EtOAc (150 ml) and washed with satd. NaHCO3. The organic layer was dried (MgSO4), concentrated and purified by ISCO to give 267 as a cream-coloured solid (0.59 g; 68%). deltaH (400 MHz, CDCl3) 3.14 (t, J=5.2, 2H), 4.29 (t, J=5.2, 2H), 6.91 (d, J=8.4, 1H), 6.93 (s, 1H), 7.22-7.27 (m, 2H), 7.43-7.51 (m, 2H), 7.65 (d, J=2.4, 1H), 8.22 (s, 1H). [M+H]+: 478
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Chloro-4-fluoroaniline, its application will become more common.
