Reaction Steps

To a solution of 1,3-dimethyl-8-ethylxanthine (416 mg) in DMF (10 ml) were added potassium carbonate (332 mg) and 4-(4-chlorobenzoyl)benzyl bromide (619 mg) and the mixture was stirred at room temperature for 21 hours. This reaction mixture was diluted with water and extracted with ethyl acetate. The extract was washed with saturated aqueous NaCl solution and dried over anhydrous sodium sulfate. The solvent was distilled off and the residue was recrystallized (ethyl acetate-ether) to provide the title compound as white powder (584 mg, 67%). 1H-NMR (CDCl3) δ: 1.30(3H,t,J=7.6Hz), 2.72(2H,q,J=7.6Hz), 3.40(3H,s), 3.61(3H,s), 5.64(2H,s), 7.21-7.80(8H,m).
