Ammonia → HCID 20524093, compound

Participants

Reaction Steps

A solution of 8 g N-benzoyl-1,3-diaminopropane, 6,7 g 3-(2-bromoethyl)indole and 5 ml anhydrous triethylamine in 15 ml anhydrous dimethylformamide is maintained for 72 hours in nitrogen atmosphere. A dilute ammonia solution and methylene chloride are then added to the reaction mixture and the organic phase is dried and evaporated. The residue is chromatographied on silicagel using as eluant methylene chloride+5% methanol+0.3% ammonia, to yield the title compound (M.pt. of the naphthalene-2-sulfonate 203°-204° with decomposition after crystallization from ethanol).
