Triethylamine → HCID 178502627, compound

Participants

Reaction Steps

To a solution of 8′-chloro-6′-(pyrimidin-4-ylamino)-2′H-spiro[cyclohexane-1,3′-imidazo[1,5-a]pyridine]-1′,5′-dione (1, 1 g, 2.89 mmol) in chloroform (30 mL) was added triethylamine (1.21 mL, 8.67 mmol) and O-methylhydroxylamine hydrochloride (241 mg, 2.89 mmol). The reaction was stirred at reflux overnight. The resulting mixture was cooled to room temperature and washed with water. The organic layer was dried over magnesium sulfate, filtered and concentrated. The crude was purified via flash column chromatography to afford 8′-chloro-1′-(methoxyimino)-6′-(pyrimidin-4-ylamino)-1′,2′-dihydro-5′H-spiro[cyclohexane-1,3′-imidazo[1,5-a]pyridin]-5′-one (Cpd. No. 132).
