Step 3: Preparation of 2, 5-dichloro-1 ,3-benzoxazole.5-chloro-1 ,3-benzoxazole-2-thiol (8.09 g, 43.6 mmol) dissolved in CHCI3 (65 mL) and stirred at ice bath for 10 minutes. Chlorine gas was bubbled into the solution for 10 minutes. The reaction mixture was further stirred at room temperature overnight. The reaction mixture was poured into ice water (70 mL) and extracted with aq. 2N NaOH (30mLx2), then ice water (30mL). The CHCI3 solution was allowed to stand for 10 minutes, then filtered through a plug of silica gel to give clear solution. The solvent was removed under reduced pressure to afford semi-oil crude product. The crude product was dissolved in CHCI3 (25 mL) and filtered through diatomaceous earth. The solvent was removed under reduced pressure to give the title compound as a solid., 22876-19-3
22876-19-3 5-Chlorobenzo[d]oxazole-2(3H)-thione 708870, abenzoxazole compound, is more and more widely used in various fields.
