Name is 5-Chlorobenzo[d]oxazole-2(3H)-thione, as a common heterocyclic compound, it belongs to benzoxazole compound, and cas is 22876-19-3, its synthesis route is as follows.
INVENTIVE EXAMPLE 41 5-Chloro-2-(4-methyl-1-homopiperazinyl)benzoxazole 5-Chloro-2-mercaptobenzoxazole (1 g) was dissolved in toluene (50 ml), N-methylhomopiperazine (3.3 ml) was added dropwise to the solution and then the mixture was stirred with heating for 2 hours. After evaporation of the solvent, the thus obtained mixture was purified by a silica gel column chromatography (methylene chloride_methanol=20:1) to obtain the title compound 5-chloro-2-(4-methyl-1-homopiperazinyl)-benzoxazole (882 mg).
22876-19-3, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,22876-19-3 ,5-Chlorobenzo[d]oxazole-2(3H)-thione, other downstream synthetic routes, hurry up and to see
