Versuchsvorschrift
Heat a mixture of 5.0 gm. of 2-cyano-6.11-dihydro-11-oxodibenz[b,e]oxepin and 4.0 gm. of Raney nickel alloy in 60 ml. of 75% (v/v) aqueous formic acid at reflux for 1.5 hours. Cool to room temperature and filter. Concentrate to small volume and extract with methylene chloride. Wash the extract with water and with 1 N sodium bicarbonate until neutral. Dry the neutral extract over sodium sulfate and concentrate to dryness to obtain the title product.
