실험 절차
As described for example 5, (5-methyl-3-phenyl-isoxazol-4-yl)-methanol (3.60 mg, 19.0 mmol) was converted using methyl 5-bromo-6-chloronicotinate instead of 6-chloronicotinonitrile to the title compound (SiO2, heptane:ethyl acetate=90:10 to 60:40, 2.83 g, 37%) which was obtained as a white solid. MS: m/e=403.3/405.2 [M+H]+.
