Sodium hydride → HCID 19102601, 화합물

참여 물질

반응 단계

A solution of 7-(2-cyanoethyl)indole (Example 14a) (4.42 g, 26 mmol) in dimethylformamide (30 ml) was added dropwise to a stirred suspension of sodium hydride (1.3 g, 60% dispersion, 32.5 mmol, washed with hexane under nitrogen) in dimethylformamide (30 ml) at 10°-15° C. The mixture was stirred for 15 minutes at ca 15° C. then a suspension of 3-[2(E)-(7-chloroquinolin-2-yl)ethenyl] benzyl chloride (Example 14b) (10.2 g, 32.5 mmol) in dimethylformamide (60 ml) was added rapidly. The dark mixture was stirred for 5 hours at room temperature, poured onto saturated ammonium chloride solution and extracted with dichloromethane. The extract was dried and evaporated under high vacuum and the residue in dichloromethane (30 ml) was applied to a silica column and eluted with ethyl acetate-hexane (1:2). The product was recrystallised from ethyl acetate-hexane, m.p. 151° C.
