Potassium Carbonate → 1-[2-(2-Methoxy-phenyl)-2-oxo-ethyl]-3-methyl-7-(3-methyl-2-buten-1-yl)-8-chloro-xanthine

Participants

Reaction Steps

1.71 g of 2-bromo-1-(2-methoxy-phenyl)-ethanone are added to a mixture of 2.00 g of 3-methyl-7-(3-methyl-2-buten-1-yl)-8-chloro-xanthine and 1.38 mg of potassium carbonate in 15 ml of N,N-dimethylformamide. The reaction mixture is stirred for eight hours at ambient temperature. After aqueous working up the crude product is purified by chromatography through a silica gel column with cyclohexane/ethyl acetate (8:1 to 8:1) as eluant.
