Versuchsvorschrift

To a solution of 3,5-difluoro-4-pyridinecarboxylic acid (15.9 mg, 0.1 mmol, Frontier Scientific) in dimethylformamide (0.1 ml) was added HATU (38 mg, 0.1 mmol) in dimethylformamide (0.2 mL), followed by N,N-diisopropylethylamine (0.050 ml, 0.286 mmol) and the resulting solution left for 5 min. Finally, a solution of 1-[(2,4-dichlorophenyl)methyl]-1H-pyrazol-3-amine (24.2 mg, 0.01 mmol, ChemCollect GmbH) in N,N-dimethylformamide (0.1 ml) was added and the resulting solution shaken for 10 min. The solution was then left to stand for 16 h at ambient temperature after which the solvent was removed. A 1:1 mixture of dimethylsulphoxide:methanol (0.6 ml) was added and the solution purified by MDAP on SUNFIRE C18 column (Method D). The appropriate fraction was concentrated in vacuo then under nitrogen flow to give the title compound (4.4 mg);
