Reaction Conditions

Reaction Steps

A mixture of 2.7 parts of 5-[(4-chlorophenyl)methyl]-2-(methylthio)-4(1H)-pyrimidinone and 3.67 parts of N-[1-(2-aminoethyl)-4-piperidinyl]-1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-amine was stirred and heated for 4 hours at 140° C. The reaction mixture was cooled and taken up in trichloromethane. The solution was purified by column-chromatography over silica gel using a mixture of trichloromethane and methanol (96:4 by volume), saturated with ammonia, as eluent. The pure fractions were collected and the eluent was evaporated. The residue was suspended in 1,1'-oxybisethane, yielding 4.5 parts (76.8%) of 5-[(4-chlorophenyl)methyl]-2-[[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]amino]-1-piperidinyl]ethyl]amino]-4(1H)-pyrimidinone monohydrate; mp. 150.6°-158.7° C. (compound 85).
