In the same manner but replacing N-(2-hydroxyphenyl)pyrrole with an equivalent amount of N-(5-chloro-2-hydroxyphenyl)pyrrole, described in Example 1, 8-chloro-4-methyl-4H-pyrrolo[2,1-c][1,4]-benzoxazine-4-acetic acid, νmaxCHCl3 2,900 - 2,500, 1,728, 1,498, 1,445 cm-1, is obtained via the intermediate ester, 8-chloro-4-methyl-4H-, pyrrolo[2,1-c][1,4]benzoxazine-4-acetic acid ethyl ester, νmaxCHCl3 1,732 cm-1.
