Based on our previous studies, 21 new halogenated 3-(4-alkylphenyl)-1,3-benzoxazine-2,4-(3H)-diones were synthesized by the reaction of salicylanilides and methyl-chloroformate. All compounds were screened in vitro against three different strains of mycobacterium, and Free-Wilson method was used to establish structure-activity relationships. 6-Bromo-3-(4-butylphenyl)-1,3-benzoxazine-2,4-(3H)-dione 3b proved to be the most active compound of the series.
