Eprazinone Dihydrochloride is a drug used to improve pulmonary function in patients with chronic bronchitis.
Definition
ChEBI: A hydrochloride obtained by combining eprazinone with two molar equivalents of hydrochloric acid.
Manufacturing Process
61.4 g of 0.2M of 1-(2-phenyl-2-ethoxy)piperazine dihydrochloride, 33.5 g
(0.25M) propiophenone, 75 g (0.25M) trioxymethylene, 120 ml of ethanol and
0.4 ml of concentrated HCl are heated under reflux for 4 to 5 hours. The
product is allowed to crystallize, then filtered and washed with alcohol. It is
dried and recrystallized from methanol containing 10% H2O.
There is thus obtained 60 g of a white crystalline powder soluble in water.
Yield: 66%. Melting point: 160°C.
