실험 절차

5-({[tert-Butyl(dimethyl)silyl]oxy}methyl)-3-[4-(trimethylstannyl)phenyl]4,5-dihydroisoxazole (0.70 g, 1.6 mmol), (5R)-3-(4-iodophenyl)-5-[(4-methyl-1H-1,2,3-triazol-1-yl)methyl]-1,3-oxazolidin-2-one (0.5 g, 1.29 mmol), tri-2-furyl phosphine (0.06 g, 0.26 mmol) and tris(dibenzylideneacetone)palladium (0) (0.12 g, 0.13 mmol) were dissolved in 1,4-dioxane (5 ml) and degassed three times. The mixture was then heated to 90° C. and stirred for 18 hr. LCMS indicated that the reaction was not yet complete, so it was cooled and an additional (0.12 g, 0.13 mmol) of tris(dibenzylidene acetone) palladium (0) was added, the mixture degassed and reheated to 110° C. for 3 hours, and 25° C. for 40 hours. The solution was concentrated in vacuo and purified by silica flash chromatography with 5-10% methanol in dichloromethane as eluent giving 0.2 g of the desired product as a yellow solid.
