Procedure

In analogy to Example 228, 6-{3-chloro-4-[3,3,3-trifluoro-2-hydroxy-1-methyl-2-(4-methyl-3-oxo-3,4-dihydro-2H-benzo[1,4]oxazin-6-yl)-propyl]-phenoxy}-nicotinic acid methyl ester (Example 229) was hydrolyzed with 1 M aqueous LiOH solution (4 h, r.t.) to give the title compound as a white solid. MS (m/e, ISP neg. ion)=535.1 [M−H+].
