5-(4-Bromo-phenyl)-3-methyl-isoxazole-4-carbaldehyde (0.285 g, 1.07 mmol) was dissolved in THF (8 mL) and the solution was cooled to −78° C. Ethynylmagnesium bromide (0.5M in THF, 2.6 mL, 1.28 mmol) was added dropwise and the reaction was allowed to warm to room temperature. After 1 hour the reaction was quenched with aqueous ammonium chloride the submitted to standard workup to yield the title compound.
