Versuchsvorschrift

A solution of m-anisidine (11.2 mL, 0.1 mol), chloroethyl ether (11.7 mL, 0.1 mol), and diisopropylethylarine (35 mL, 0.2 mol) in toluene (100 mL) was stirred at reflux for 72 h. The precipitate was removed by filtration and washed with toluene (100 mL). The combined toluene solutions were concentrated in vacuo and purified by distillation (120–130° C., 0.2 Torr) to afford the intermediate 4-(3-methoxyphenyl)-morpholine (14.9 g, 77%).
