Procedure

To a solution of 400 mg 1-[(5-Chloro-pyridin-2-ylcarbamoyl)-methyl]-5-[2-(2-methoxy-ethoxy)-ethoxymethyl]-1H-pyrazole-3-carboxylic acid tert-butyl ester in 5 ml DCM, 15 ml TFA were added at RT. After 3 h 30 ml toluene were added and the solvents were removed under reduced pressure. The residue was then three times codistillied with toluene and subjected to the next reaction step without further purification.
