Procedure

4-Hydroxy-2-methyl-N-(5-methyl-2-thiazolyl)-2H-naphtho[2,1-e]-1,2-thiazine-3-carboxamide-1,1-dioxide was prepared analogous to Example 22 from 4-hydroxy-2-methyl-2H-Naphtho[ 2,1-e]-1,2-thiazine-3-carboxylic acid methyl ester-1,1-dioxide and 2-amino-5-methyl-thiazole. Yield: 67% of theory, m.p. 249°-250° C (decomp.; from xylene).
