Reaction Steps

To a solution of 5-(3-bromobenzyl)-3-methyl-1,2,4-oxadiazole 1098 (0.50 g, 1.97 mmol) in dioxane (1 mL), under an atmosphere of Argon, was added Bis(tri-t-butylphosphine)palladium(0) (0.15 g, 0.295 mmol) followed by the addition of 2-tert-butoxy-2-oxoethylzinc chloride (0.5 M in diethyl ether, 4.92 mmol, 9.84 mL). The mixture was allowed to stir under argon for 20 hours and the volatiles were removed under reduced pressure. The residue was taken up in EtOAc (10 mL) and washed with water (2×5 mL), brine (2×5 mL) and dried over Na2SO4. The Na2SO4 was removed by filtration and the volatiles removed under reduced pressure. The crude material was purified by normal phase chromatography 0-50% EtOAc/Hexanes to give 0.300 g tert-butyl 2-(3-((3-methyl-1,2,4-oxadiazol-5-yl)methyl)phenyl)acetate 1099. 1H NMR 300 MHz CDCl3: δ 7.40-7.18 (m, 4H), 4.17 (s, 2H), 3.51 (s, 2H), 2.36 (s, 3H), 1.43 (s, 9H).
