実験手順

To a solution of Pyridazin-4-ylamine (30 mg, 0.31 mmol, [Cas. No. 20744-39-2]) in DMF (3 mL) at 0° C. was added sodium hydride (20 mg, 0.5 mmol, 60% disp. in mineral oil). After stirring at 0° C. for 15 min. a solution of 3-[5-(2-Fluoro-phenyl)-pyridin-2-yloxy]-azetidine-1-carboxylic acid 4-nitro-phenyl ester (102 mg, 0.25 mmol) in DMF (4 mL) was added dropwise. After stirring for 16 hrs at ambient temperature the reaction mixture was concentrated in vacuo, diluted with ethyl acetate (50 mL) and washed sequentially with sat. aqueous sodium hydrogen carbonate solution (2×50 mL) then sat. sodium chloride solution (50 mL). Mixture dried over magnesium sulphate and filtered. Filtrate solvents were removed in vacuo and the residue was purified by preparative HPLC to give the title compound (15 mg, 16%)
