Production Methods
Thionyl chloride (885 g, 7.5 mol)And N, N-dimethylformamide (270 ml) were added to a solution of 5-chloro-2-mercaptobenzoxazole (540 g, 2.903 mol) in dichloromethane (5 L) at 5-10 ° C.Stirred until a clear solution was formed and the reaction solution was stirred at room temperature for 4 hours.After completion of the reaction, the reaction solution was poured into 4 L of ice water, neutralized to neutral with sodium bicarbonate in 1 hour, and extracted with dichloromethane (2.5 L * 2).The organic layer was washed with brine, dried over sodium sulfate and dried to give the crude product. The crude product was washed with n-hexane (2 L * 2) at -20 ° C, filtered and dried to give yellow liquid 2, 5-dichlorobenzo (496.8 g, 91.0percent).Thionyl Chloride (540 mL) and Dimethyl formamide (270 mL) were added to a stirred mixture of 5-Chloro-1, 3-benzoxazole-2-thiol (540 g, 2.903 moles) and dichloromethane (5 liter) at 5-10° C. and stirred till clear solution was observed.
