Versuchsvorschrift

2.4 g of ethyl 2-(4-[2-(3-[4-fluorophenyl]-1-heptylureido)ethyl]phenoxy)-2-methylpropionate was dissolved in 50 mL of ethanol and 30 mL of 1N aqueous sodium hydroxide was added. The resulting solution was heated at reflux for 30 minutes, cooled to room temperature, acidified with 100 ml of 2N aqueous HCl and extracted with CH2Cl2. The organic extract was washed with water and brine, dried over magnesium sulfate and concentrated in vacuo. The resulting solid was recrystalized from diethyl ether/hexane to yield 1.1 g of the title compound as a white powder; m.p. 162-4° C.; 1H NMR (CD3OD, δ, 300 MHz): 7.35-6.7 (7H, m, aromatic), 3.48 (2H, t, NCH2), 3.24 (2H, t, NCH2), 2.76 (2H, t, ArCH2), 1.5-1.1 (10H, m, (CH2)5CH3), 1.45 (6H, s, (CH3)2C), 0.83 (3H, t, (CH2)5CH3).
