Reaction Steps

0.61 ml of diisopropyl azodicarboxylate are added to a mixture of 594 mg of 3-methyl-7-(2-butyn-1-yl)-8-bromo-xanthine, 353 mg of (indolizin-2-yl)-methanol and 826 mg of triphenylphosphine in 30 ml of tetrahydrofuran. The reaction mixture is stirred for two hours at ambient temperature. For working up it is diluted with methylene chloride, added to 6 g silica gel and chromatographed through a silica gel column with petroleum ether/ethyl acetate (7:3 to 1:5) as eluant.
