Procedure
In analogy to the procedures described for the preparation of intermediate A-1 [B], 1-amino-cyclopropanecarboxylic acid{(S)-5-[5-chloro-3-fluoro-2-(5-methyl-[1,2,4]oxadiazol-3-yl)-phenyl]-indan-1-yl}-amide (example 24) was coupled with pyridazine-4-carboxylic acid to yield the title compound as light yellow solid. MS: 533.2 (MH+, 1Cl).
