Procedure
As described for example 1e, 6-(3-butyl-5-methyl-isoxazol-4-ylmethoxy)-pyridazine-3-carboxylic acid methyl ester (120 mg, 0.39 mmol) was converted, using rac-tetrahydrofuran-3-amine instead of isopropylamine, to the title compound (130 mg, 92%) which was obtained as a light yellow oil after purification by chromatography (silica, 0 to 5% methanol in dichloromethane). MS: m/e=361.5 [M+H]+.
