Product 1

HCID 60143099Pyridazine-4-carboxylic acid (1-{(rac)-6-[5-chloro-3-fluoro-2-(5-methyl-[1,2,4]oxadiazol-3-yl)-phenyl]-2,3-dihydro-benzofuran-3-ylcarbamoyl}-cyclopropyl)-amide

Procedure

In analogy to the procedure described for the preparation of intermediate A-1 [B], 1-amino-cyclopropanecarboxylic acid{(rac)-6-[5-chloro-3-fluoro-2-(5-methyl-[1,2,4]oxadiazol-3-yl)-phenyl]-2,3-dihydro-benzofuran-3-yl}-amide (example 45) has been coupled with pyridazine-4-carboxylic acid to yield the title compound as yellow solid. MS: 535.1 (MH+, 1Cl).
