| Reactant | 2-Bromo-4-(trifluoromethyl)pyridine | HCID 2781543 | — |
| Reactant | 4-Ethynyl-5-methyl-3-phenyl-isoxazole | HCID 53434647 | — |
| Product | HCID 24783416 | HCID 24783416 | 76% |
Reaction Steps
As described for example 11c, 4-ethynyl-5-methyl-3-phenyl-isoxazole (92 mg, 0.50 mmol) was converted (using 2-bromo-4-(trifluoromethyl)pyridine instead of 2-chloro-4-iodopyridine) to the title compound (SiO2, heptane:ethyl acetate=95:5 to 0:100, 124 mg, 76%) which was obtained as an off-white solid. MS: m/e=329.3 [M+H]+.
