Reaction Steps
A mixture of 6-chloro-3-[1-[4-(2,3-dihydro-1H-indol-3-yl)butan-1-yl]-1,2,3,6-tetrahydropyridin-4-yl]-1H-indole 30b (4.9 g), triethylamine (3.7 g), and THF (200 ml) was cooled (5° C.), and the mixture was added a solution of acetyl chloride (1.0 g) in THF (50 ml). The reaction mixture was allowed to warm to room temperature, filtered and concentrated in vacuo. The residue was purified on silica gel eluted with ethyl acetate-ethanol-triethylamine (90:10:5) to give the crude product, which was recrystallized (methanol-ethyl acetate) to give the title compound (2.7 g).
