Procedure
As described for example 1e, 6-(3-butyl-5-methyl-isoxazol-4-ylmethoxy)-pyridazine-3-carboxylic acid methyl ester (110 mg, 0.36 mmol) was converted, using (S)-tetrahydrofuran-3-amine hydrochloride instead of isopropylamine, to the title compound (100 mg, 77%) which was obtained as a colourless oil after purification by chromatography (silica, 0 to 3.5% methanol in dichloromethane). MS: m/e=361.0 [M+H]+.
