2-Chlorobenzoxazole Chemical Properties,Usage,Production

Chemical Properties

clear yellow liquid

Uses

2-Chlorobenzoxazole was used in the synthesis of 2-(2-naphthylamino)benzoxazole via reaction with 2-amino-1-naphthalenesulfonic acid.

Synthesis

2382-96-9

615-18-9

General procedure for the synthesis of 2-chlorobenzoxazole from 2-mercaptobenzoxazole: 2-mercaptobenzoxazole (10 mmol, 1.51 g) was suspended in SOCl2 (50 mL), and a few drops of DMF were added as catalyst. The reaction mixture was heated to reflux for 5 hours. After completion of the reaction, the solvent was removed by evaporation. The crude product was purified by silica gel column chromatography (eluent: petroleum ether/EtOAc, 10:1) to afford the target compound as a colorless oil in 69.7% yield.

Purification Methods

Purify it by fractional distillation, preferably in a vacuum. [Siedel J Prakt Chem 42 456 1890, Katz J Am Chem Soc 75 712 1953, Meyer & Sigel J Org Chem 42 2769 1977, Beilstein 27 H 43, 27 II 17.]
