Procedure

To a stirred mixture of 34.5 parts of 9-[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]methyl]-1-piperidinyl]ethyl]-9H-purine-8-thiol and 180 parts of N,N-dimethylformamide were added portionwise 3.2 parts of a sodium hydride dispersion 50%. Upon completion, stirring was continued for 0.5 hours at room temperature. 11.5 Parts of iodomethane were added dropwise. After complete addition, the whole was stirred for 1 hour. The reaction mixture was poured into water. The product was extracted with 4-methyl-2-pentanone. The extract was dried, filtered and evaporated. The residue was crystallized from acetonitrile. The product was filtered off and dried, yielding 28.3 parts (80%) of 9-[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]methyl]-1-piperidinyl]ethyl]-8-(methylthio)-9H-purine; mp. 133.1° C. (507).
