Iodoacetamide → HCID 14013412, compound

Participants

Reaction Steps

A mixture of 9.3 parts of 2-iodoacetamide, 20.0 parts of 3-[(4-fluorophenylmethyl]-2-(4-piperidinylmethyl)-3H-imidazo[4,5-b]pyridine dihydrochloride, 17.0 parts of sodium hydrogen carbonate and 200 parts of ethanol was stirred for 3 hours at at reflux temperature. The salts were filtered off and the filtrate was evaporated. The residue was purified by column chromatography over silica gel using a mixture of trichloromethane, methanol and ammonium hydroxide (90:9:1 by volume) as eluent. The pure fractions were collected and the eluent was evaporated. The residue was crystallized from a mixture of 2,2'-oxybispropane and 2-propanone. The product was filtered off and dried in vacuo at 60° C., yielding 8.5 parts (44.5%) of 4-[[3-[(4-fluorophenyl)-methyl]-3H-imidazo[4,5-b]pyridin-2-yl]methyl]-1-piperidineacetamide; mp. 153.4° C. (148).
