Participants

Reaction Steps

A solution of sym. octahydroacridine-4-carboxamide (1.8 gm.) in pyridine (17 ml.) was treated with hydrogen sulphide for 5 mins. The reaction mixture was treated with phosphorus pentasulphide (1.4 g.) and heated at reflux for 45 mins maintaining a slow stream of hydrogen sulphide throughout. The cooled reaction mixture was evaporated and the residue treated with 10% sodium hydroxide until alkaline. The aqueous solution was extracted with chloroform (3 × 50 ml.) and the combined extracts washed with brine, dried and evaporated and the residual solid recrystallised from di-isopropyl ether giving the title compound as a pale yellow powder (0.3 g. 16%) m.p. 104°-6° (solidifies and remelts at 148°). (Found: C, 68.69; H, 7.54; N, 10.98%. C14H18N2S requires: C, 68.26; H, 7.36; N, 11.37%).
