Reaction Steps

7.5 Parts of 6-chloro-N4 -[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]amino]-1-piperidinyl]ethyl]-4,5-pyrimidinediamine and 3.6 parts of urea were heated together till about 220° C. during 10 minutes. The resulting melt was cooled and suspended in water. The solid was filtered off, washed with water and ethanol and recrystallized from a mixture of N,N-dimethylacetamide, ethanol and water, yielding 3.9 parts (49.9%) of 6-chloro-9-[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]amino]-1-piperidinyl]ethyl]-7.9-dihydro-8H-purin-8-one; mp. 266.2° C. (compound 144).
