Versuchsvorschrift

A mixture of phenylglycidyl ether (8.0 g), N-benzyltyramine hydrochloride (13.0 g) and triethylamine (7.5 ml) in isopropanol (200 ml) was heated to reflux for 3hours. The solvent was evaporated and toluene was added to the residue. Volatile material was evaporated. The residue was purified by chromatography on K60 silica (300 g) using a gradient mixture of methanol in dichloromethane (1 to 2% methanol). Thus was obtained 4-[2-(N-benzyl-N-(2-hydroxy-3-phenoxypropyl)amino)ethyl]phenol (16.5 g) as an oil which slowly crystallised, m.p. 103°-5° C.: NMR: 2.55-2.85[m,6H, CHCH2NHCH2CH2 ]; 3.65-4.05 [m,5H, PhOCH2CHOH +PhCH2 ]; 6.65-7.4[m,14H, aromatic H].
