Procedure

As described for example 11c, 4-ethynyl-5-methyl-3-phenyl-isoxazole (92 mg, 0.50 mmol) was converted (using 2-chloropyrazine instead of 2-chloro-4-iodopyridine) to the title compound (SiO2, heptane:ethyl acetate=95:5 to 0:100, 78 mg, 60%) which was obtained as a light yellow solid. MS: m/e=262.1 [M+H]+.
