실험 절차

A solution of 2-[4-[[4-(2-chloroethoxy)phenyl]methyl]phenyl]oxazole (1.7 g, 4.4 mmol) in 2-butanone (18 mL) was stirred as sodium iodide (7 g, 44 mmol) was added. The reaction was heated at reflux for 2 days. The reaction was concentrated. The residue was dissolved in ethyl acetate and washed with water. The combined organic layers were dried and concentrated. The residue was recrystallized from methanol to give 1.4 g of 2-[4-[[4-(2-iodoethoxy)phenyl]methyl]phenyl]oxazole, 1H NMR (400 MHz, CDCl3) δ 7.97 (d, 2H), 7.68 (s, 1H), 7.27 (d, 2H), 7.21 (s, 1H), 7.13 (d, 2H), 6.82 (d, 2H), 4.22 (t, 2H), 3.96 (s, 2H), 3.39 (t, 2H).
