Introduction of a new synthetic route about 1750-45-4

With the rapid development of chemical substances, we look forward to future research findings about 1750-45-4

5-Chloro-6-hydroxybenzo[d]oxazol-2(3H)-one, cas is 1750-45-4, it is a common heterocyclic compound, the benzoxazole compound, its synthesis route is as follows.,1750-45-4

5-chloro-6-hydroxy-1,3-benzoxazol-2(3H)-one (0.93 g, 5 mmol) and imidazole (1.00 g, 15 mmol) were dissolved in dimethylformamide (10 mL) with stirring under inert atmosphere. Triisopropylsilylchloride (1.15 g, 6 mmol) was added and the resulting solution was stirred for 3 days. The reaction mixture was partitioned between water and heptane. The organic layer was washed with water and dried over magnesium sulphate, filtrated and concentrated, to give 1.45 g (85%) of the subtitled compound as a grey solid. APCI-MS: m/z 342 [MH+]

With the rapid development of chemical substances, we look forward to future research findings about 1750-45-4
