실험 절차

To a solution of 350 mg 5-[2-(2-Methoxy-ethoxy)-ethoxymethyl]-2H-pyrazole-3-carboxylic acid tert-butyl ester in 5 ml of DMF and 46 mg of sodium hydride (60% in mineral oil) were added at RT. After stirring for 20 min at room temperature 290 mg of 2-Bromo-N-(5-chloro-pyridin-2-yl)-acetamide were added. The reaction was stirred at room temperature for 3 h. Then 10 ml of water were added and the mixture was filtered through a chem elut® cartridge by elution with DCM. After concentration under reduced pressure the crude was subjected to the next reaction without further purification. Yield: 400 mg.
