Reaktionsschritte
Heat together a mixture of one equivalent of 8-bromo-1,3-di-n-butyl-xanthine and three to four equivalents of benzylamine at 160°-180° C. until thin layer chromatography shows that no starting xanthine remains. Cool. Triturate with ethanol and water to yield 8-benzylamino-1,3-di-n-butyl-xanthine.
