Reaction Steps

4-Benzyl-3-methyl-1,2,3-oxadiazol-5-one (0.600 g) and ethynyltri-n-butyltin (2.5 ml) were dissolved in xylene (10 ml) and heated to 140° C. under argon for 16 h. The solvent was then evaporated and the residue was chromatographed over silica gel. Elution with a gradient of 0 to 10% acetone/toluene gave the product as a yellow oil (0.189 g); dH (CDCl3) 0.8-1.7 (27H, m), 3.77 (3H, s), 4.00 (2H, s), 6.09 (1H, s), 7.10-7.40 (5H, m).
