실험 절차

A mixture of 0.7 parts of isothiocyanatomethane, 3.7 parts of N-[1-(2-aminoethyl)-4-piperidinyl]-9-[(4-fluorophenyl)methyl]-9H-purin-8-amine and 90 parts of tetrahydrofuran was stirred for 4 hours at room temperature. After evaporation, the residue was purified by column chromatography over silica gel using a mixture of trichloromethane and methanol, saturated with ammonia, (95:5 by volume) as eluent. The first fraction was collected and the eluent was evaporated. The residue was crystallized from acetonitrile. The product was filtered off and dried, yielding 1.3 parts (29%) of N-[2-[4-[[9-[(4-fluorophenyl)methyl]-9H-purin-8-yl]amino]-1-piperidinyl]ethyl]-N'-methylthiourea; mp. 205.5° C. (compound 179).
