Versuchsvorschrift
As described for example 1a, 5-methyl-3-phenyl-isoxazole-4-carboxylic acid chloride (0.5 g, 2.26 mmol) was converted, using 6-aminomethyl-nicotinic acid methyl ester (313 mg, 1.88 mmol) (J. Med. Chem. 2002, 45, 5005-5022), instead of 2-picolylamine, to the title compound (0.56 g, 85%) which was obtained as a white solid. MS: m/e: 352.0 [M+H]+.
