Reaction Steps
In analogy to Example 5, 6-[2-(2-chloro-4-hydroxy-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-4-methyl-4H-benzo[1,4]oxazin-3-one (Example 56, step 4) was reacted with 4-methoxycarbonyl-phenylboronic acid, copper-(II)-acetate and pyridine to give the title compound as a white solid. MS (m/e, ISP neg. ion)=548.2 [M−H+]
