m-Chloroperbenzoic acid → HCID 53948062, compound

Participants

Reaction Steps

In a manner similar to that described in Example II, 1.19 grams (0.0055 mole) of m-chloroperbenzoic acid is added to a solution of 1.29 grams (0.005 mole) of 9-cyano-5,6-dihydrobenzo[5,6]cyclohepta[1,2-b]pyridin-11-one in 20 milliliters of chloroform and the resulting mixture stirred at ambient temperature for several days with an addition of an about 0.5 gram portion of m-chloroperbenzoic acid after the first 24 hours. At the end of this period the mixture is washed, dried and evaporated to obtain a 9-cyano-5,6-dihydrobenzo[5,6]cyclohepta[1,2-b]-pyridin-11-one N-oxide intermediate as residue.
