実験手順
N-(3-Chloro-phenyl)-4-hydroxy-2-methyl-2H-naphtho[2,1-e]-1,2-thiazine-3-carboxamide-1,1-dioxide was prepared analogous to Example 1 from 4-hydroxy-2-methyl-2H-naphtho[2,1-e]-1,2-thiazine-3-carboxylic acid ethyl ester-1,1-dioxide and 3-chloroaniline. Yield: 71% of theory; m.p. 248°-249° C (decomp.; from ethylene chloride).
