Article abstract of DOI:10.1055/s-1987-27990

Various N-substituted derivatives of 2H-1,4-benzothiazin-3(4H)-one are obtained in high yields employing functionalized alkyl halides and potassium tert-butoxide in dimethylformamide.The method is mild, regioselective and tolerates a variety of functional groups.
