Procedure
As described for example 11c, 4-ethynyl-5-methyl-3-phenyl-isoxazole (92 mg, 0.50 mmol) was converted (using 2-bromo-5-methylpyridine instead of 2-chloro-4-iodopyridine) to the title compound (SiO2, heptane:ethyl acetate=95:5 to 0:100, 75 mg, 55%) which was obtained as a light brown solid. MS: m/e=275.2 [M+H]+.
