Versuchsvorschrift

To a suspension of 4-chloro-2-fluorobenzoic acid (0.3494 g, 2.00 mmol) in methylene chloride (10 ml) were added t-butylamine (0.32 ml, 3.05 mmol) and HOBt (0.3248 g, 2.40 mmol), and then WSC HCl (0.4596 g, 2.40 mmol) was added and stirred for 3 hours. The reaction mixture was added into water and extracted three times with ethyl acetate. The combined extracts were dried over MgSO4. The solvent was evaporated and the residue was purified by silica gel chromatography (hexane/ethyl acetate=5/1) to give the title compound (0.4403 g; 96%).
