Versuchsvorschrift
WSC HCl (1.15 g, 6 mmol) was added to a mixture of 2,4-difluorobenzoic acid (0.95 g, 6 mmol), 2-fluoro-1,1-dimethylethylamine hydrochloride (J. Med. Chem., 34, 29-37(1991): 0.77 g, 6 mmol), HOBt (0.81 g, 6 mmol) and triethylamine (0.91 g, 9 mmol) in methylene chloride (15 ml), and stirred at room temperature for 3 hours. The reaction mixture was concentrated, diluted with ethyl acetate and washed with saturated aqueous NaHCO3, 1N hydrochloric acid, saturated aqueous NaHCO3 and brine, successively, dried over MgSO4 and concentrated under a reduced pressure. The residue was purified by silica gel chromatography (hexane/ethyl acetate=20/1) to give the title compound (0.61 g; 44%).
