Definition
ChEBI: Buterizine is a diarylmethane.
Manufacturing Process
A mixture of 10.3 parts of 1-chloro-4-(chloromethyl)-2-nitrobenzene, 25.2
parts of 1-(diphenylmethyl)piperazine and 120 parts of ethanol is stirred and
refluxed for 4 h. The reaction mixture is cooled and evaporated. The residue is
taken up in about 100 parts of water and the product is extracted with
methylbenzene. The extract is washed with water, dried, filtered and
evaporated. The residue is purified by column-chromatography over silica gel
using trichloromethane as eluent. The pure fractions are collected and the
eluent is evaporated. The residue is crystallized from a mixture of 2,2'-
oxybispropane and hexane (1:2 by volume). The product is filtered off,
washed with hexane and dried, yielding 19.6 parts of 1-(4-chloro-3-
nitrophenylmethyl)-4-(diphenylmethyl)piperazine; melting point 101.6°C.
During 20 h, gaseous ethanamine is bubbled through a stirred and hot (60-
70°C) mixture of 1-(4-chloro-3-nitrophenylmethyl)-4-
(diphenylmethyl)piperazine and dimethylsulfoxide. The reaction mixture is
cooled and poured onto ice-water. The precipitated product is filtered off,
washed with water and taken up in methylbenzene. The latter is dried, filtered
and evaporated. The residue is purified by column-chromatography over silica
gel using a mixture of trichloromethane and methanol as eluent. The pure
fractions are collected and the eluent is evaporated, yielding 4-[4-
(diphenylmethyl)-1-piperazinylmethyl]-N-ethyl-2-nitrobenzenamine; melting
point 128.2°C (crystallized from 2,2'-oxybispropane).
A solution of 4-[4-(diphenylmethyl)-1-piperazinylmethyl]-N-ethyl-2-
nitrobenzenamine in methanol is hydrogenated at normal pressure and at
room temperature with Raney-nickel catalyst. After the calculated amount of
hydrogen is taken up, the catalyst is filtered off and the filtrate is evaporated, yielding 4-[4-(diphenylmethyl)-1-piperazinylmethyl]-N1-ethyl-1,2-
benzenediamine.
A mixture of 4-[4-(diphenylmethyl)-1-piperazinylmethyl]-N1-ethyl-1,2-
benzenediamine and acetic acid is stirred at room temperature till all solid
enters solution. Then there are added pentyl ethanimidate hydrochloride and
stirring is continued first for 1 h at room temperature and further for 1 h at
reflux. The reaction mixture is evaporated and the residue is stirred in water.
The whole is alkalized with a sodium hydroxide solution and the product is
extracted with dichloromethane. The extract is dried, filtered and evaporated.
The residue is purified by column-chromatography over silica gel using a
mixture of trichloromethane and methanol as eluent. The pure fractions are
collected and the eluent is evaporated. The product is filtered off and dried,
yielding 5-[4-(diphenylmethyl)-1-piperazinylmethyl]-1-ethyl-2-butyl-1Hbenzimidazole;
melting point 124.8°C (crystallized from 4-methyl-2-
pentanone).
