실험 절차
N-(5-Ethyl-4-methyl-2-thiazolyl)-4-hydroxy-2-methyl-2H-naphtho[2,1-e]-1,2thiazine-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 methylester-1,1-dioxide and 2-amino-5-ethyl-4-methyl-thiazole. Yield: 63% of theory; m.p. 253°-255° C (decomp.; from ethanol).
