실험 절차

10.0 g (0.066 mol) of 1,6-hexanedithiol are added to a suspension of 3.6 g (0.026 mol) of potassium carbonate in 15 ml of dimethylacetamide. The suspension is heated to 85° C., and a solution of 3.6 g (0.013 mol) of 1-(4-chlorophenyl)-2-methyl-2-morpholin-4-yl-propan-1-one in 20 ml of dimethylacetamide is added dropwise over 20 min. After stirring for 18 h, the reaction mixture is cooled, diluted with ethyl acetate (60 ml), and filtered. The filtrate is washed with water (3×50 ml), dried over MgSO4, and concentrated i.v. (85° C./5 mm Hg). The resulting oil is purified by flash chromatography on silica gel (hexane/ethyl acetate 85:15) to a pale yellow oil which crystallizes to a colorless solid upon standing. m.p. 61-64° C. The structure is confirmed by the 1H-NMR spectrum (CDCl3): δ [ppm] 1.31 (s, 6H), 1.35 (t, SH), 1.4-1.8 (m, 8H), 2.53 (q, 2H), 2.57 (t, 4H), 3.00 (t, 2H), 3.69 (t, 4H), 7.24 (d, 2H), 8.50 (d, 2H).
