Mode opératoire

To a solution of 260 mg 4-(2,2,2-Trifluoro-ethoxy)-1H-pyrazole-3,5-dicarboxylic acid diethyl ester in 4 ml absolute DMF 33.5 mg of a 60% suspension of NaH in mineral oil were added under an argon atmosphere. The mixture was stirred for 15 min at RT. Then 209 mg 2-Bromo-N-(5-chloro-pyridin-2-yl)-acetamide were added and the mixture stirred for 2 h at RT. After concentration in vacuo the residue was directly subjected to the next reaction step without further purification.
