Versuchsvorschrift
In a manner analogous to that described in Example 2b), the reaction of (R)-5-[2,4-difluoro-5-(6-trifluoromethyl-benzo oxazol-2-yl)-phenyl]-6,6-difluoro-5,7,7-trimethyl-[1,4]oxazepan-3-one (163 mg, 332 μmol) with Lawesson's reagent (145 mg, 359 μmol) yielded the title compound (113 mg, 67% yield as a white solid. MS (ISP): m/z=507.1 [M+H]+.
