Procedure

A mixture of 16 parts of 6-chloro-7-[(4-fluorophenyl)methyl]-8-[[1-(phenylmethyl)-4-piperidinyl]methyl]-7H-purine, 4.65 parts of ethyl carbonochloridate and 180 parts of methylbenzene was stirred for 2 hours at reflux temperature. After cooling, the reaction mixture was treated with ammonium hydroxide and the product was extracted with methylbenzene. The extract was washed with water, dried, filtered and evaporated, yielding 18.7 parts (100%) of ethyl 4-[[6-chloro-7-[(4-fluorophenyl)methyl]-7H-purin-8-yl]methyl]-1-piperidinecarboxylate as a residue (compound 28).
