As described for example 44, 4-methyl-6-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-pyridazine-3-carboxylic acid (200 mg, 0.61 mmol) was converted, using isopropylamine instead of 4-amino-tetrahydropyran, to the title compound (SiO2, heptane:ethyl acetate=100:0 to 60:40, 90 mg, 40%) which was obtained as a white solid.
