Participants

Reaction Steps

A mixture of 1.65 parts of 2-(phenoxymethyl)oxirane, 8.9 parts of 3-(2-ethoxyethyl)-2-(1-piperazinylmethyl)-3H-imidazo[4,5-b]pyridine and 40 parts of 2-propanol was stirred for 20 hours at reflux temperature. The reaction mixture was evaporated and the residue was purified by column chromatography over silica gel using a mixture of trichloromethane and methanol (95:5 by volume) as eluent. The pure fractions were collected and the eluent was evaporated. The residue was crystallized from 2,2'-oxybispropane. The product was filtered off and dried, yielding 1.36 parts (31.0%) of 4-[[3-(2-ethoxyethyl)-3H-imidazo[4,5-b]pyridin-2-yl]methyl]-α-(phenoxymethyl)-1-piperazineethanol; mp. 102.5° C. (compound 118).
