A solution of HATU (46 mg, 0.12 mmol) in DMF (200 μl) was added to 2,6-dichlorobenzoic acid (22 mg, 0.11 mmol, Avocado) followed by DIPEA (50 μl, 0.286 mmol) and left to stand for 5 min at ambient temperature. A solution of 1-[(2,4-dichlorophenyl)methyl]-1H-pyrazol-4-amine (Art Chem GmbH; 53 mg, 0.22 mmol) in DMF (200 μl) was then added and the solution left to stand for 16 h at ambient temperature. The solvent was removed using a Genevac. The sample was dissolved in 1:1 MeOH:DMSO (0.6 ml) and purified by MDAP on a standard C18 column (method D) using acetonitrile-water with a TFA modifier. The solvent was evaporated in vacuo using a Genevac to give the title compound (35 mg); LCMS (System 3): MH+=414, tRET=1.18 min.
