実験手順

Potassium carbonate (23 mg, 165 μmol) was added to a solution of 3-[5-(3-hydroxy-phenyl)-pyridin-2-yloxy]-azetidine-1-carboxylic acid pyridin-3-ylamide (20 mg 55 μmol), in DMF (0.5 mL). 2-Bromoethyl methyl ether (6 μL, 66 μmol) was added and the reaction mixture was heated to 100° C. in microwave synthesiser for 1 hr. The reaction mixture was allowed to cool and solvent removed in vacuo. The crude product was purified by preparative HPLC to afford the title product as a colourless solid (6.7 mg, 29%).
