Reaction Steps

As described for example 97, 5-[3-(4-fluoro-phenyl)-5-hydroxymethyl-isoxazol-4-ylmethoxy]-2-methyl-2H-pyrazole-3-carboxylic acid (100 mg, 0.29 mmol) was converted, using 3-methyl-3-oxetanamine instead of rac-3-aminotetrahydrofuran, to the title compound (60 mg, 50%) which was obtained as a white foam. MS: m/e=415.1 [M−H]−.
