[(6R,7S)-2-fluoro-6-methyl-9-(2-morpholin-4-yl-ethyl)-8-oxo-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-7-yl]-carbamic acid tert-butyl ester was deprotected according to the procedure in example 42b. The resulting (6R,7S)-7-amino-2-fluoro-6-methyl-9-(2-morpholin-4-yl-ethyl)-6,7-dihydro-9H-5-oxa-9-aza-benzocyclohepten-8-one was reacted with 2,2-dimethyl-N-(2,2,3,3,3-pentafluoro-propyl)-malonamic acid in analogy to the procedure described in example 2b to yield N-[(6R,7S)-2-fluoro-6-methyl-9-(2-morpholin-4-yl-ethyl)-8-oxo-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-7-yl]-2,2-dimethyl-N′-(2,2,3,3,3-pentafluoro-propyl)-malonamide, MS m/e (%): 569.3 (M+H+, 100).
