Procedure

3-Fluoro-4-hydroxybenzoic acid ethyl ester (0.20 g, 1.1 mmol) and N-(2-chloroethyl)morpholine (0.22 g, 1.2 mmol) were dissolved in dry DMF (10 ml). Potassium carbonate (1.88 g, 5 mmol) was added and the turbid reaction mixture was stirred overnight at 40° C. under an argon atmosphere. The reaction mixture was concentrated under reduced pressure and ethyl acetate was added to the residue followed by washing with NaHCO3 (½ sat., 3×), water, brine, dried (MgSO4), filtered. The crude oil was purified over silica gel (CH2Cl2/MeOH 39:1): colorless oil 0.16 g (49%);
