실험 절차

A mixture of 1.5 g of 11-hydroxy-10,11-dihydro-5,10-imino-[5H]-dibenzo (a,d) cycloheptene dl cis, 60 ml of benzene and 3 g of silver silicate was refluxed with stirring for 45 minutes and then 1.5 g of silver silicate were added and reflux was continued for another hour. The mixture was filtered hot and the filter was washed with methylene chloride. The combined filtrates were washed with 2N hydrochloric acid and the acid phase was made alkaline with sodium hydroxide. The mixture was extracted with methylene chloride and the organic phase was dried over magnesium sulfate and distilled to dryness under reduced pressure. The residue was chromatographed over silica gel and eluted with a 95-5 mixture of chloroform-methanol to obtain 780 mg of 10,11-dihydro-5,10-imino-[5H]-dibenzo (a,d) cycloheptene-11-one dl melting at 100° C identical to that of Example 1.
