Reaction Steps

As described for example 58b, 5-methyl-3-pyrimidin-4-yl-isoxazole-4-carboxylic acid ethyl ester (500 mg, 2.1 mmol) was converted, instead of 2-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-isonicotinic acid methyl ester, to the title compound (321 mg, 73%) which was obtained as an off white solid. MS: m/e=204.1 [M−H]−.
