Reaction Conditions

Reaction Steps

5-tert-Butyl-2-methyl-2H-pyrazol-3-ylamine (10s) (4.8 g, 31 mmol) and carbonyl diimidazole (4.6 g, 32 mmol) were partially dissolved in DCE (100 mL) and heated at 70° C. for 2 hours. The reaction was cooled and 2-aminomethyl-phenylamine (9s) (4.2 g, 34 mmol) was added and the reaction was stirred 14 hours. The reaction was concentrated to remove the solvent and then partitioned between EtOAc and 0.5N HCl (60 mL). The organic phase was washed with NH4Cl and water and dried (MgSO4). The solution was concentrated and recrystallized from EtOAc (200 mL) to provide the desired product (5s) (4.6 g, 49% yield).
