Related Products of 38487-86-4, These common heterocyclic compound, 38487-86-4, name is 2-Amino-4-chlorobenzonitrile, its 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.
5-Chloro-2-(lH-tetrazol-5-yl)aniline: 2-Amino-4-chlorobenzonitrile (1000 mg, 6.6 mmol), sodium azide (555 mg, 8.5 mmol) and triethylamine hydrochloride (1175 mg, 8.5 mmol) were taken up in 15 mL of toluene. The suspension was heated to 100 0C overnight. After cooling, the reaction mixture was washed 3 times with 5 mL portions of water. The combined aqueous fractions were acidified with concentrated hydrochloric acid. The desired 5-Chloro-2-(lH-tetrazol-5-yl)aniline precipitated from aqueous solution and was isolated by filtration (1090 mg, 85% yield). 1H NMR (500 MHz, DMSO-d6) delta 7.73 (d, IH), 6.97 (d, IH), 6.74 (dd, IH); MS (electrospray) m/z 196 (M+H).
Statistics shows that 2-Amino-4-chlorobenzonitrile is playing an increasingly important role. we look forward to future research findings about 38487-86-4.
