実験手順
2-[2-(2-Chloroethoxy)ethoxy]ethanol 31 (9.273 g, 55 mmol) and benzylamine (26.3 mL, 240 mmol) were dissolved in absolute acetonitrile (150 mL) whereupon potassium carbonate (25.0 g, 180 mmol) was added. The suspension was heated at reflux with vigorous stirring under an argon atmosphere for 18 hours. The suspension was allowed to cool to room temperature, diluted with acetonitrile (100 mL) and filtered through a Celite™ pad. The acetonitrile was removed under reduced pressure and the unreacted benzylamine distilled from the concentrated pale greenish oil under high vacuum (90° C., 5 torr). The resulting viscous oil (14.2 g) was purified by flash chromatography using 13% methanol in dichloromethane as the eluent. Fractions contained the desired product (Rf=0.45) were combined, solvent removed under reduced pressure, and the residue dried in vacuo to yield the title compound as a viscous oil (10.1 g, 77%). CIMS (MH+): m/e 240. 1H-NMR (CDCl3): δ 7.31 (m, 5H, phenyl), 3.79 (s, 2H, CH2-Ph), 3.70-3.61 (m, 12 H, OCH2CH2O). 13C-NMR (CDCl3): δ 140.3, 129.0, 128.8, 127.6, 73.3, 70.9, 70.8, 70.7, 62.0, 54.4, 49.0.
