실험 절차
A mixture of 2.8 parts of 2-(methylthio)thiazolo[5,4-b]pyridine and 5.5 parts of N-[1-(2-aminoethyl)-4-piperidinyl]-1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-amine was stirred for 24 hours at 140° C. The reaction mixture was purified by column chromatography over silica gel using a mixture of trichloromethane and methanol, saturated with ammonia, (97:3 by volume) as eluent. The pure fractions were collected and the eluent was evaporated. The residue was crystallized from acetonitrile. The product was filtered off and dried, yielding 1.9 parts (25%) of N-[2-[4-[[1-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-yl]amino]-1-piperidinyl]ethyl]thiazolo[5,4-b]pyridin-2-amine; mp. 203.5° C. (compound 103).
