Procedure

A solution of [4-(4-benzyloxycarbonylaminobutyl)phenoxy]acetic acid ethyl ester 23 (0.3 g, 0.78 mmol), 2-(2-hydroxyethylamino)ethanol 24 (0.15 mL, 1.6 mmol), and ethanol (20 mL) was heated at 70° C. for 72 hours. Solvent was evaporated in vacuo. The residue was purified by flash chromatography (silica gel, dichloromethane/methanol, 100:5, v/v) to provide [4-(4-{[N,N-bis-(2-hydroxyethyl)carbamoyl]methoxy}phenyl)-butyl]carbamic acid benzyl ester 25 [0.19 g, 100% based on the recovered starting material (0.13 g)] as a pale yellow solid.
