Procedure

By reacting 5-amino-3,4-dimethyl-isoxazole with 3-carbomethoxy-4-hydroxy-2-methyl-thieno[2,3-e]-1,2-thiazine 1,1-dioxide for 14 hours in a manner analogous to that described in Example 1, there is obtained N-(3,4-dimethyl-5-isoxazolyl)-4-hydroxy-2-methyl-2H-thieno[2,3-e]-1,2-thiazine-3-carboxamide 1,1-dioxide of decomposition point 206°-208° C. (recrystallization from benzene.
