실험 절차

The compound was also accessible, inter alia, by first reacting 7-benzyl-3-methylxanthine with 1-chloro-5-hexanone under the reaction conditions described above to give 7-benzyl-3-methyl-1-(5-oxohexyl)-xanthine (yield 90.4% of theory, melting point: 82°-84° C.) and then reductively methylating the oxohexyl side chain with methylmagnesium chloride in anhydrous ether analogously to Example 9 (yield: 60.2% of theory; melting point: 108°-110° C.).
