実験手順

A mixture of 2.95 parts of 3,4-pyridinediamine, 16 parts of 9-[(4-fluorophenyl)methyl]-N-[1-(2-isothiocyanatoethyl)-4-piperidinyl]-9H-purin-8-amine, and 90 parts of tetrahydrofuran was stirred and refluxed overnight. The reaction mixture was evaporated. 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 pure fractions were collected and the eluent was evaporated, yielding 10.5 parts of N-(4-amino-3-pyridinyl)-N'-[2-[4-[[9-[(4-fluorophenyl)methyl]-9H-purin-8-yl]amino]-1-piperidinyl]ethyl]thiourea (compound 182).
