2,4,6-Trimethylpyridine → HCID 178521852, compound

Participants

Reaction Steps

A suspension of EDCI (192 mg, 0.679 mmol), 2,4,6-trimethylpyridine (224 mg, 1.85 mmol), and 7-hydroxyimidazo[1,2-a]pyridine-3-carboxylic acid (110 mg, 0.617 mmol) in DMF (2 mL) was stirred at ambient temperature for two hours. A solution of 1-benzyl-1H-indazol-4-amine (138 mg, 0.617 mmol) in DMF (2 mL) was added, and the resulting mixture was sonicated for 5 minutes. The heterogeneous mixture was stirred at ambient temperature overnight, then diluted with EtOAc, and washed twice with 1M aqueous hydrochloric acid, followed by brine. The organic layer was concentrated and subjected to chromatography on silica with 10% MeOH/DCM as eluent to provide 1.5 mg of desired product. MS (ES+APCI) m/z=384 (M+H) detected.
