Reaction Steps
As described for example 112a, 3-pyridin-2-yl-isoxazole-4-carboxylic acid ethyl ester (9.6 g, 44 mmol), instead of 6-[3-(5-fluoro-pyridin-2-yl)-5-methyl-isoxazol-4-ylmethoxy]-pyridazine-3-carboxylic acid ethyl ester, was converted to the title compound (6.5 g, 79%) which was obtained as an off-white solid. MS: m/e=189.3 [M−H]−.
