Definition
ChEBI: 1-(4-chlorophenyl)-4-(dimethylamino)-2,3-dimethyl-2-butanol is an organic amino compound and a member of benzenes.
Manufacturing Process
A solution of 0.2 mol (33 g) of 3-methyl-4-dimethylamino-butanone-(2)
[produced according to Mannich, Arch. Pharm., vol. 265, page 589 (1927)] in
50 cc absolute ether was added dropwise, while stirring and cooling with ice,
to a Grignard solution of 0.4 mol p-chlorobenzylmagnesium-chloride which
was produced from 64.5 g p-chlorobenzyl-chloride and 9.8 g magnesium in
200 cc absolute ether. The reaction product was heated for an additional onehalf hour under reflux to bring the reaction to completion, and thereafter the
reaction mixture was decomposed into an ether phase and an aqueous phase
with about 50 cc concentrated hydrochloric acid and about 200 g ice. The
ether phase was discarded and the aqueous phase was adjusted to an alkaline
pH with ammonia and then thoroughly extracted with ether. After
concentrating the united, dried ether extract solutions, the oily residue was
fractionally distilled. The reaction product was obtained in the form of a
colorless oil having a boiling point of 179° to 181°C. The yield was 48.5 g
corresponding to 95% of theory.
The hydrochloride addition salt of the above reaction product was prepared in
customary fashion, that is, by reaction with hydrochloric acid, followed by
fractional crystallization from a mixture of alcohol and ether. The two possible
racemic forms were obtained thereby. The difficultly soluble racemate had a
melting point of 169° to 170°C and the more readily soluble racemate had a
boiling point of 145° to 148°C.
