Procedure

Step-2: N-{4-[5-cyclopropyl-3-(trifluoromethyl)-1H-pyrazol-1-yl)-3,5-difluorophenyl)-3-oxobutanamide (1 g, 2.6 mmol) and N,N-Dimethylformamide dimethylacetal (1.7 g, 14.2 mmol) were mixed and stirred at rt for overnight. Workup (AcOEt/H2O) followed by purification on 60-120 mesh silicagel using AcOEt and Peteher (1:1) as eluent afforded N-{4-[5-cyclopropyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]-3,5-difluorophenyl}-2-[(dimethylamino)methylene]-3-oxobutanamide (0.7 g).
