Chloroform → (+/-)-trans-3-[(3-Cyclohexen-1-yl)carbonyl]-1,2,3,4,4a,8,9,14a-octahydropyrido[4',3':2,3]indolo[1,7-ab][1]benzazepine

Participants

Reaction Steps

Triethylamine (10 ml.) was added with stirring to a solution of 5.5 g. (±)-trans-1,2,3,4,4a,8,9,14a-octahydropyrido[4',3':2,3]indolo[1,7-ab][1]benzazepine in 100 ml. chloroform, followed by addition, with stirring, of 5.76 g. (0.04 moles) 3-cyclohexene-1-carbonyl chloride in 10 ml. chloroform. The mixture was refluxed 2 hours then cooled and water was added. The organic layer was separated, dried over K2CO3, and evaporated to dryness in vacuo. Trituration of the residual oil in hexane gave (±)-trans-3-[(3-cyclohexen-1-yl)carbonyl]-1,2,3,4,4a,8,9,14a-octahydropyrido[4',3':2,3]indolo[1,7-ab][1]benzazepine, m.p. 156.5°-158.5° .
