실험 절차

DMF (8 ml) and diisopropylethylamine (738 mg) were added to 4-chloro-2-methyl-2H-pyrazole-3-carboxylic acid (916 mg, 5.7 mmol) and TBTU (1.83 g), and the mixture was stirred at r.t. (10 min). 2-Phenyl-imidazo[1,2-c]pyrimidin-7-ylamine (400 mg, 1.9 mmol) was added and the mixture was stirred at r.t. overnight. The reaction mixture was then poured on water (35 ml), and the mixture was extracted with ethyl acetate. The combined organic layers were dried (Na2SO4) and evaporated. The title compound (45 mg, 6.7%) was isolated from the residue by column chromatography (silica gel, heptane:ethyl acetate=100:0-60:40), followed 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)=353.1 [M+H+].
