Versuchsvorschrift

4-Aminobenzeneethanol (20.2 g), 2-chloroethyl ether (21.1 g), N,N-diisopropylethylamine (38.1 g) and potassium iodide (48.8 g) in DMF were heated to 80° under nitrogen for 60 h. The solvent was evaporated and the residue (~143 g) was purified by FCC eluting with ER-CX (1:1→1:0) to give the title compound as a pink-white solid (17.7 g) m.p. 57°.
