These common heterocyclic compound, 84859-27-8, name is 5-Chloro-N1-methylbenzene-1,2-diamine, 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. Quality Control of 5-Chloro-N1-methylbenzene-1,2-diamine
6-Chloro-l-methyl-l,3-dihydro-benzoimidazol-2-one (61): A mixture of 4- chloro-N2-methyl-benzene-l,2-diamine (60) (100 mg, 0.64 mmol, 1 eq), triphosgene (95 mg, PATENT Attorney Docket No.: 019934-00601 OUS0.32 mmol, 0.5 eq), TEA (0.26 ml) in THF(2 ml) was stirred at rt for 4 hours. The reaction solution was washed with ethyl acetate and concentrated to provide 6-chloro-l -methyl- 1,3- dihydro-benzoimidazol-2-one (61).
The synthetic route of 5-Chloro-N1-methylbenzene-1,2-diamine has been constantly updated, and we look forward to future research findings.
