Since the synthetic compounds of benzoxazolin-2-one (
1
) have a wide range of 
biological activities, the synthesis of various important synthetic analogues has become 
the main goal of many researchers. One of the most widely used compounds in the 
production of biologically active compounds are substituted benzoxazolines. 
Benzoxazoline compounds include antimalarial, antiparasitic, antimicrobial [1], 
antiviral [2], anticancer [3] and many other biologically active compounds. 
The analysis of scientific sources shows that the synthesis of sulfonamides (
4-10
) is 
not reported in the literature. We have propylated of benzoxazoline (
