Potassium Carbonate → HCID 20061097, compound

Participants

Reaction Steps

1.4 g of 1,3-dimethyl-6-{2-[3-(4-nitrophenyl)propylamino]ethylamino}-2,4(1H,3H)-pyrimidinedione hydrochloride (Compound e) were dissolved in 5 ml of water, followed by the addition of potassium carbonate to render the solution alkaline. The solution was then extracted with chloroform. The thus-obtained chloroform solution was concentrated to dryness, followed by the addition of 0.6 g of p-methoxybenzyl bromide, 3 ml of triethylamine and 20 ml of isopropanol. The resultant mixture was heated for 8 hours under reflux. The solvent was distilled off under reduced pressure and the residue was directly subjected to chromatographic purification on a silica gel (eluent: chloroform/methanol=40/1, by volume), thereby obtaining 0.55 g of 1,3-dimethyl-6-{2-[N-(4-methoxybenzyl)-3-(4-nitrophenyl)propylamino]ethylamino}-2,4(1H,3H)-pyrimidinedione.
