실험 절차

A mixture of 20.65 parts of 1-(phenylmethyl)-4-piperidineacetic acid hydrochloride, 19.5 parts of 6-chloro-N4 -[(4-fluorophenyl)methyl]-4,5-pyrimidinediamine and 510 parts of phosphoryl chloride was stirred and refluxed for 13 hours. The reaction mixture was evaporated. The residue was poured into ice water. The whole was treated with sodium hydroxide. The product was extracted with 4-methyl-2-pentanone. The extract was washed with water, dried, filtered and evaporated. The residue was purified by column chromatography over silica gel using a mixture of trichloromethane and methanol, saturated with ammonia, (97:3 by volume) as eluent. The first fraction was collected and the eluent was evaporated, yielding 23.6 parts (75%) of 6-chloro-9-[(4-fluorophenyl)methyl]-8-[[1-(phenylmethyl)-4-piperidinyl]-methyl]-9H-purine as an oily residue (compound 1).
