反応手順
In analogy to Example 64, step 7, trifluoromethanesulfonic acid 3-chloro-4-[2-(4-ethyl-3-oxo-3,4-dihydro-2H-benzo[1,4]oxazin-6-yl)-3,3,3-trifluoro-2-hydroxy-1-methyl-propyl]-phenyl ester (Example 64, step 6) was reacted with 4-chloro-3-(ethoxycarbonyl)phenylboronic acid (70° C., 5.5 h) to give title compound as a white solid. MS (m/e)=596.3 [M+H+].
