1,1'-Carbonyldiimidazole → Imidazole-1-carboxylic acid [5-(2-tert-butyl-pyridin-4-yl)-4-methyl-thiazol-2-yl]-amide

Participants

Reaction Steps

A mixture of 5-(2-tert-butyl-pyridin-4-yl)-4-methyl-thiazol-2-ylamine (Step 1.2) (1 g, 4.05 mmol) and 1,1′-carbonyldiimidazole (0.984 g, 6.07 mmol, 1.5 eq) in DCM (50 mL) is stirred for 4 h at reflux and allowed to cool. The resulting precipitate is collected by filtration to provide 1.26 g of the title compound as white solid: ESI-MS: 340.2 [M−H]−; tR=2.85 min (System 1).
