PROCESS FOR PREPARING 2-METHYL-3-ALKOXY-CARBIMIDOYL-4-HYDROXY-2H-1,2-BENZOTHIAZINE-1,1-DIOXIDE |
| abstract |
2-Methyl-3-alkoxycarbonyl-4-hydroxy-2H-1,2-benzothiazine-1,1-dioxides of general formula I can be conveniently prepared by reacting a saccharin-2-acetic acid alkyl ester of general formula II in a solvent reacted with magnesium alkoxide at higher temperatures and the resulting reaction mixture is reacted at low temperatures with a methylating agent. The compounds can be used as intermediates for drugs. |
