Versuchsvorschrift

Beneath a solution of 20 g of trans-decahydroquinoline in 100 ml of benzene is introduced a layer consisting of a solution of 5.8 g of sodium hydroxide in 100 ml of water. While stiring vigorously and cooling to 5°-10°C, 20 g of chlorothioformic acid allyl ester are then added dropwise to the mixture. Upon completion of the reaction, stirring is continued for 3 hours, the phases are separated, the benzene phase is washed until neutral, dried, and the benzene evaporated in vacuo. The residual oil is distilled in vacuo to yield 24 g (70% of theory) of 1-(allylthiocarbonyl)-trans-decahydroquinoline (b.p. 110°-116°C/0.2 Torr).
