Procedure

In analogy to Example 5, 6-[2-(2-chloro-5-hydroxy-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-4-methyl-4H-benzo[1,4]oxazin-3-one (Example 1, step 4) was reacted with 3-chloro-4-methoxycarbonylphenylboronic acid, copper-(II)-acetate and pyridine to give the title compound as a colorless foam. MS (m/e)=585.9 [M+H+].
