Versuchsvorschrift

A solution of 7-[4-(6-chloronicotinoyl)benzyl]-1,3-dimethylxanthine (196 mg) and 4-piperidinopiperidine (102 mg) in pyridine (10 ml) was stirred at 60° C. for 5 hours. This reaction mixture was poured in water and extracted with ethyl acetate. The extract was washed with water, dried and concentrated. The residue was purified by silica gel column chromatography (ethyl acetate: acetone: triethylamine 1:1:0.1) to provide the title compound (108 mg).
