実験手順
As described for example 112a, 6-{[3-(5-chloro-pyridin-2-yl)-5-methyl-isoxazol-4-ylmethyl]-amino}-pyridazine-3-carboxylic acid ethyl ester (405 mg, 1.1 mmol) was converted, instead of 5-[3-(4-chloro-phenyl)-isoxazol-4-ylmethoxy]-pyrazine-2-carboxylic acid methyl ester, to the title compound (346 mg, 92%) which was obtained as an off white solid. MS: m/e=343.9 [M−H]−.
