Reaction Steps

A solution of 4-[[4-(2-oxazol yl)phenyl]methyl]phenol (2.2 g, 8.75 mmol) and 2-chloroethylbromide (10 g, 70 mmol) in acetonitrile as stirred as cesium carbonate (22.8 g, 70 mmol) was added. The reaction was heated at reflux for 3 days. The reaction was diluted with water. The product, 2-[4-[[4-(2-chloroethoxy)phenyl]methyl]phenyl]oxazole (2.7 g), was isolated by filtration, 1H NMR (400 MHz, CDCl3) δ 7.97 (d, 2H), 7.68 (s, 1H), 7.35 (m, 2H), 7.21 (s, 1H), 7.13 (d, 2H), 6.82 (d, 2H), 4.22 (t, 2H), 3.96 (s, 2H), 3.79 (t, 2H).
