Participants

Reaction Steps

5-(5-Bromo-2-methyl-pentanoylamino)-3-(4-methoxy-phenyl)-pyrazole-1-carboxylic acid tert-butyl ester (280.0 mg, 0.6 mmol, 1.0 eq) was dissolved in DCM (3 mL). Triethylamine (80 μL, 0.6 mmol, 1.0 eq) and 1-[1,4]-diazepan-1-yl-ethanone (158 μL, 170.0 mg, 1.2 mmol, 2.0 eq) were added and the mixture was stirred at room temperature for 24 hours, then at 50° C. for 16 hours. NaHCO3 saturated solution was added and the organic layer separated and collected. Evaporation of the solvent gave a crude product purified using SiO2 column (elution DCM, DCM:MeOH 99:1 to 96:4) obtaining the title product (181.3 mg, yield 54%).
