Procedure
To a stirred mixture of 4.6 parts of N4 -[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]amino]-1-piperidinyl]ethyl]-4,5-pyrimidinediamine, 2.25 parts of N,N-diethylethanamine and 195 parts of dichloromethane were added dropwise 1.75 parts of carbonothioic dichloride. Upon completion, stirring was continued for 3 hours at reflux temperature. 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. The residue was converted into the hydrochloride salt in ethanol and 2-propanol. The salt was filtered off and dried, yielding 1 part (15.4%) of 9-[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]amino]-1-piperidinyl]ethyl]-7,9-dihydro-8H-purine-8-thione trihydrochloride.dihydrate; mp. 244.7° C. (compound 143).
