1,1'-Carbonyldiimidazole → HCID 59526207, compound

Participants

Reaction Steps

A solution of (6-bromopyridin-2-yl)acetic acid (Example 235, Step 2) (30 mg, 0.39 mmol) in dimethylformamide (3 mL) was charged with carbonyldiimidazole (338 mg, 2.08 mmol) and maintained at room temperature for 1 hour. A solution of 1-methyl-1H-pyrazol-4-amine (175 mg, 1.81 mmol) in dimethylformamide (2 mL) was added and the reaction was stirred overnight at room temperature. The reaction was then directly purified by reverse phase HPLC (10-100% acetonitrile/water+0.05% TFA modifier) to yield the title compound.
