Procedure
A mixture of p-(2-aminoethoxy)phenol hydrochloride (1.89 g) triethylamine (1.01 g) and 1,2-epoxy-3-phenoxypropane (1.5 g) was heated under reflux for 24 hours. The reaction mixture was cooled and the solvent was evaporated. The residue was partitioned between dichloromethane (100 ml) and 10% w/v potassium carbonate solution. The organic layer was separated, dried (MgSO4), and the solvent was evaporated. The residual oil was dissolved in ethyl acetate and dry hydrogen chloride was passed through the solution until no further solid precipitated. The precipitate was collected and recrystallised from methanol and ethyl acetate to give p-(2-[2-hydroxy-3-phenoxypropylamino]-ethoxy)phenol hydrochloride (0.53 g), mp, 171°-72° C.; microanalysis: found C,60.3; H,6.7; N,4.0; Cl, 10.6%; required for C17H22NClO4 : C,60.1; H,6.5; N,4.1; Cl,10.5%.
