Procedure

As described for example 11c, 4-ethynyl-5-methyl-3-phenyl-isoxazole (92 mg, 0.50 mmol) was converted (using 4-bromo-2-isopropylthiazole instead of 2-chloro-4-iodopyridine) to the title compound (SiO2, heptane:ethyl acetate=95:5 to 0:100, 23 mg, 15%) which was obtained as a yellow oil. MS: m/e=309.3 [M+H]+.
