Versuchsvorschrift

To a solution of N-propyl-4-[4-(trifluoromethyl)phenyl]-1,3-thiazole-2-amine (700 mg, 2.44 mmol) in N,N-dimethylformamide (5 mL) was added sodium hydride (100 mg, in oil, 2.5 mmol) at room temperature and the mixture was stirred at room temperature for 1 hr. Ethyl 3-(4-{[4-(chloromethyl)benzyl]oxy}-2-fluorophenyl)propanoate (700 mg, 2.0 mmol) was added and the mixture was further stirred at room temperature for 2 hr. The reaction mixture was poured into 1N hydrochloric acid and the mixture was extracted with ethyl acetate. The organic layer was concentrated and the residue was purified by preparative HPLC. The obtained fraction was concentrated, neutralized with 10% aqueous sodium hydrogencarbonate solution, and extracted with ethyl acetate. The ethyl acetate layer was filtered with a Presep Dehydration tube (Wako Pure Chemical Industries, Ltd.) and concentrated to give the title compound as a yellow oil.
