実験手順
As described for example 112b, 6-(5-methyl-3-pyrimidin-4-yl-isoxazol-4-ylmethoxy)-pyridazine-3-carboxylic acid (38 mg, 0.12 mmol) was converted, instead of 6-[3-(5-fluoro-pyridin-2-yl)-5-methyl-isoxazol-4-ylmethoxy]-pyridazine-3-carboxylic acid, using ethanolamine instead of 2-amino-2-methyl-1-propanol, to the title compound (18 mg, 42%) which was obtained as a light yellow foam. MS: m/e=357.1 [M+H]+.
