Reaction Steps
4-(2-Benzyloxyethyl)-2-phenyloxazole (670 mg, 239 mmol) was dissolved in THF (10 mL) and cooled to −78° C. before adding n-butyllithium (1.15 mL of a 2.5 M solution in hexanes). The resulting orange solution was warmed to −65° C., stirred 45 min, and then propyl iodide (1.22 g, 7.17 mmol, 0.70 mL) was added via syringe. The solution was warmed to ambient temperature and stirred 90 min. The mixture was concentrated and the product purified by flash chromatography (100 mL SiO2, hexanes to 20% EtOAc/hexanes) and obtained as a colorless oil (340 mg, 44%): Rf=0.49 in 20% EtOAc/hexanes; 1H NMR (500 MHz, CDCl3) δ 8.00-7.96 (m, 2H), 7.42-7.26 (m, 8H), 4.54 (s, 2H), 3.76 (t, J=7.0 Hz, 2H), 2.83 (t, J=7.0 Hz, 2H), 2.64 (t, J=7.0 Hz, 2H) 1.68 (sextet, J=7.0 Hz, 2H), 0.96 (t, J=7.0 Hz, 3H).
