실험 절차

A solution of hexaethylene glycol monobenzyl ether from above (22.3 g) in anhydrous THF (100 ml) was added to a suspension of 50% NaH (3.5 g) in anhydrous THF (100 ml). The suspension was stirred at ambient temperature for 30 min and then a solution of triethylene glycol methyl tosyl ether from above (22.0 g) in THF (100 ml) was added dropwise. The mixture was refluxed under nitrogen overnight, cooled to ambient temperature, quenched with water (500 ml), and extracted with diethyl ether (3×300 ml). The ether extracts were combined, dried (sodium sulfate), and concentrated in vacuo to give nonaethylene glycol benzyl methyl ether as an oil (27 g, 88%), 1H-NMR (CDCl3) δ: 7.31 (m, 5, 5 phenyl CH), 4.54 (s, 2, benzyl CH2), 3.62-3.52 (m, 36, 18 CH2O), 3.35 (s, 3, CH3).
