m-Chloroperbenzoic acid → HCID 54117372, compound

Participants

Reaction Steps

To a solution of 1.04 grams (0.005 mole) of benzo[5,6]cyclohepta[1,2-b]pyridin-11-one in 20 milliliters of chloroform was added 1.19 grams (0.0055 mole) of m-chloroperbenzoic acid and the resulting solution stirred at room temperature for 24 hours. At this time an additional 0.6 gram of m-chloroperbenzoic acid was added and the mixture stirred for 5 hours; thereafter, another 0.3 gram of m-chloroperbenzoic acid was added and the mixture stirred overnight. The resulting reaction mixture was then washed twice with 10 percent aqueous sodium hydroxide, twice with water and the washed solution dried over magnesium sulfate. The mixture was filtered to remove drying agent and the solvent removed under reduced pressure to obtain 0.75 gram of benzo[5,6]cyclohepta[1,2-b]pyridin-11-one N-oxide intermediate as residue.
