실험 절차

A mixture of 5 parts of 7-(2-chloroethyl)-3,7-dihydro-1,3-dimethyl-1H-purine-2,6-dione, 4 parts of 3-(4-piperidinyl)-1H-indole, 8 parts of sodium carbonate, 1 part of potassium iodide and 120 parts of 4-methyl-2-pentanone was stirred and refluxed overnight. The reaction mixture was cooled, water was added and the layers were separated. The organic phase was dried, filtered and evaporated. The residue was purified by column-chromatography over silica gel using a mixture of trichloromethane and methanol (95:5 by volume) as eluent. The pure fractions were collected and the eluent was evaporated. The residue was crystallized from 4-methyl-2-pentanone, yielding 4 parts (50%) of 7-[2-[4-(1H-indol-3-yl)-1-piperidinyl]ethyl]-3,7-dihydro-1,3-dimethyl-1H-purine-2,6-dione; mp. 201.2° C. (compound 1).
