Reaction Steps

As described for example 91h, 5-[3-(4-fluoro-phenyl)-5-hydroxymethyl-isoxazol-4-ylmethoxy]-2-methyl-2H-pyrazole-3-carboxylic acid methyl ester (100 mg, 0.28 mmol) was converted, using 2,2,3,3,3-pentafluoropropylamine instead of 4-aminotetrahydropyran, to the title compound (115 mg, 87%) which was obtained as a brown oil. MS: m/e=477.0 [M−]−.
