Procedure

TBTU (75 mg) and diisopropylethylamine (75 mg) were added to a solution of 1-methyl-5-(2-phenyl-imidazo[1,2-a]pyridin-7-ylcarbamoyl)-1H-pyrazole-4-carboxylic acid (70 mg) in DMF (2 ml), and the mixture was stirred at r.t. (30 min). Pyrrolidine (14 mg) was added to the brown solution, and the reaction mixture was stirred at r.t. overnight. Water was added and the mixture was extracted several times with ethyl acetate. The combined organic layers were dried (Na2SO4), and evaporated. The title compound (43 mg, 54%) was isolated from the residue by preparative, inverse-phase HPLC (Agilent Zorbax XdB-C18 column, time per run ˜7 min, flow rate 30 ml/min, solvent gradient H2O/CH3CN=95:5-5:95). MS (m/e)=415.3 [M+H+].
