Allyl bromide → HCID 13136259, compound

Participants

Reaction Steps

93 mg of 6-(N-ethylamino)-beta-carboline-3-carboxylic-acid-ethylester in 8 ml of absolute ethanol is heated together with 49 mg of 1,5-diaza-[5.4.0]bicycloundec-5-ene and 50 mg of allyl bromide under nitrogen for 2 h at 70° C. After evaporation, the substance is distributed in ethyl acetate and saturated sodium bicarbonate solution. The organic phase is dried, filtered and concentrated. The residue is chromatographed by means of 80 g of silica gel with methylene-chloride/ethanol (12/1) as the eluant, and, after recrystallizing out of ethyl-acetate/ether, 56 mg of 6-(N-allyl-N-ethylamino)-beta-carboline-3-carboxylic-acid-ethylester is obtained (m.p. 190°-192° C.).
