Reaction Steps

To a solution of 1.0 gm (4.4 mMol) 5-amino-3-(1-methyl-1,2,3,6-tetrahydropyridin-4-yl)-1H-indole in 60 mL tetrahydrofuran were added 0.67 mL (4.8 mMol) triethylamine and the solution was cooled to 0° C. To this solution were then added 0.32 mL (4.6 mMol) acetyl chloride and the reaction mixture was stirred at ambient temperature for 18 hours. The reaction mixture was filtered and concentrated under reduced pressure to give a dark oil. The oil was treated with water to give a black gum. This residue was purified by radial chromatography (2 mm, silica), eluting with 100:10:1 dichloromethane:methanol:ammonium hydroxide, to give 0.20 gm (16.9%) of the title compound as a yellow solid.
