Reaction Steps

The same procedure was carried out as in Example (1g), except that 5-(3-{(6-fluoro-9-methoxy-3,4-dihydro-2H-benzo[b][1,4]dioxepin-7-yl)-[4-(5-methyl[1,2,4]oxadiazol-3-yl)phenylamino]methyl}-5-oxo-4,5-dihydro-[1,2,4]triazol-1-yl)-1H-pyrazole-4-carboxylic acid ethyl ester and 0.1% acetic acid were used instead of respectively 2-(3-{(2-fluoro-4,5-dimethoxyphenyl)-[4-(5-methyl-[1,2,4]oxadiazol-3-yl)phenylamino]methyl}-5-oxo-4,5-dihydro-[1,2,4]triazol-1-yl)benzoic acid and 0.1% trifluoroacetic acid, to give the title compound as a light yellow solid.
