Reaction Steps

4-{[5-(4-Chloro-phenyl)-6-(2,2,2-trifluoro-ethoxy)-pyridine-3-carbonyl]-amino}-piperazine-1-carboxylic acid tert-butyl ester (1.047 g, 2.03 mmol) was combined with dichloromethane (25 mL) to give a white suspension. Subsequently trifluoroacetic acid (7.4 g, 5 ml, 64.9 mmol) was added at 0° C. and the reaction mixture was stirred at 0° C. for 2 h. The reaction mixture was concentrated in vacuo and the residue was crystallized from ethyl acetate and n-heptane to afford the title compound (1.0 g, quant.) as white solid.
