Participants

Reaction Steps

To a mixture of 711 mg (2.01 mmole) of 8-chloro-11-(1-acetyl-4-piperidylidene)-6,11-dihydro-5H-benzo[5,6] cyclohepta[1,2-b]pyridine in 30 ml of dry CH2Cl2 at -10° C. and under a nitrogen atmosphere was added 246 mg (1.60 mmole) of m-chloroperoxybenzoic acid. After 95 min. the mixture was taken up in CH2Cl2 and washed once with 10% aqueous sodium bisulfite and once with 10% aqueous sodium hydroxide. It was dried over magnesium sulfate, filtered, and concentrated in vacuo. The product was purified via flash chromatography (MeOH in CH2Cl2) and recrystallized from ethyl acetate/hexanes to give 175 mg of the title compound as a hemi-ethyl acetate solid. (m.p. 90.5°-93° C.)
