2-Chloro-6-fluorobenzoic acid → 2-Chloro-N-[1-({5-chloro-2-[(phenylmethyl)oxy]phenyl}methyl)-1H-pyrazol-3-yl]-6-fluorobenzamide

Participants

Reaction Steps

To a solution of 2-chloro-6-fluorobenzoic acid (18 mg, 0.1 mmol, Aldrich) in DMF (0.1 ml) was added a solution of HATU (38 mg, 0.1 mmol) in DMF (0.2 ml). After 5 min, DIPEA (0.050 ml, 0.27 mmol) was added to the mixture. To the mixture was added a solution of 1-({5-chloro-2-[(phenylmethyl)oxy]phenyl}methyl)-1H-pyrazol-3-amine (for a preparation see Intermediate 55)(0.1 mmol) in DMF (0.1 ml). After shaking for 10 min, the resulting solution was allowed 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 C18 column using Acetonitrile-Water with a TFA modifier (Method D). The solvent was evaporated in vacuo using the Genevac to give the title compound; LCMS (System 3) MH+=470/472, tRET=1.32 min.
