Reaction Steps
Using the method of Example 1, 11.9 g (0.1 mol) of benzoxazole were reacted, with addition of 0.5 g of montmorillonite KSF, with chlorine gas at 100° C. After addition of 1.1 times the molar amount of chlorine gas, GC showed complete conversion into 2-chlorobenzoxazole. Further introduction of chlorine gas (an additional 1.0 times the molar amount) at 120-125° C. resulted in 80.6% conversion into 2,6-dichlorobenzoxazole.
