1,3-Propanediamine, N'-(ethylcarbonimidoyl)-N,N-dimethyl-, monohydrochloride → HCID 57597184, compound

Participants

Reaction Steps

A solution of 6-(aminomethyl)-N-{3-chloro-4-[(3-fluorobenzyl)oxy]phenyl}-5H-pyrrolo[3,2-d]pyrimidin-4-amine dihydrochloride (150 mg), (2E)-4-(dimethylamino)but-2-enoic acid hydrochloride (105 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (244 mg), 1-hydroxybenzotriazole monohydrate (196 mg) and triethylamine (0.30 mL) in N,N-dimethylformamide (5 mL) was stirred at room temperature for 2 days. Water was added to the reaction system and the mixture was extracted with ethyl acetate. The organic layer washed with saturated brine, dried over magnesium sulfate and concentrated under reduced pressure, and the residue was separated and purified by column chromatography (basic silica gel, eluent, methanol:ethyl acetate=1:9→1:4) to give the title compound (104.2 mg) as pale-brown powder crystals.
