Procedure

A mixture of 1.9 parts of 1-(2-chloroethyl)-4-methoxybenzene, 5 parts of 7-[(4-fluorophenyl)methyl]-8-(4-piperidinylmethyl)-7H-purin-6-ol dihydrobromide, 4 parts of sodium carbonate and 45 parts of N,N-dimethylacetamide was stirred overnight at 70° C. After cooling, the reaction mixture was filtered over diatomaceous earth and the filtrate 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. The residue was crystallized from acetonitrile. The product was filtered off and dried, yielding 2.2 parts (46%) of 7-[(4-fluorophenyl)methyl]-8-[[1-[2-(4-methoxyphenyl)ethyl]-4-piperidinyl]methyl]-7H-purin-6-ol; mp. 122.2° C. (compound 62).
