tranylcypromine Usage And Synthesis

Originator

Parnate,SKF,UK,1960

Manufacturing Process

A solution containing 167 grams of stabilized styrene and 183 grams of ethyl diazoacetate is cooled to 0°C and dropped into 83.5 grams of styrene with stirring, in a dry nitrogen atmosphere, at 125° to 135°C. This produced the ester ethyl 2-phenylcyclopropanecarboxylate.
A solution of the above ester (207.8 grams) and 64.5 grams of sodium hydroxide in 80 cc of water and 600 cc of ethanol is refluxed for 9 hours. The carboxylic acid of 2-phenylcyclopropane is liberated with 200 cc of concentrated hydrochloric acid. The 2-phenylcyclopropanecarboxylic acid contains 3 to 4 parts of the trans isomer to 1 part of the cis isomer. The acid is recrystallized from hot water. The pure trans isomer comes out as crystalline material (solid) while the cis isomer stays in solution. A solution of 4.62 grams of 2-phenylcyclopropanecarboxylic acid in 15 cc of dry benzene is refluxed with 4 cc of thionyl chloride for 5 hours, the volatile liquids are removed and the residue once more distilled with benzene. Fractionation of the residue yields the carbonyl chloride of 2- phenylcyclopropane.
A mixture of 15 grams of technical sodium azide and 50 cc of dry toluene is stirred and warmed and a solution of 10 grams of 2- phenylcyclopropanecarbonyl chloride in 50 cc of dry toluene is added slowly. Inorganic salts are filtered and washed well with dry benzene and the solvents are removed under reduced pressure. The RCON3 compound produced undergoes the Curtius rearrangement to RNCO + N2. The residual isocyanate is a clear red oil of characteristic odor. It is cooled to 10°C and treated cautiously with 100 cc of 35% hydrochloric acid whereupon RNCO + H2O gives RNH2 + CO2.After most of the evolution of carbon dioxide has subsided the mixture is refluxed for 13 hours, the cooled solution is diluted with 75 cc of water and extracted with three 50 cc portions of ether. The acid solution is evaporated under reduced pressure with occasional additions of toluene to reduce foaming.
The almost dry residue is cooled to 0°C and made strongly alkaline with a 50% potassium hydroxide solution. The amine is extracted into several portions of ether, dried over potassium hydroxide, the solvent removed, and the base fractioned. Reaction of the base with a half-molar quantity of sulfuric acid gives the sulfate.

Therapeutic Function

Psychostimulant

World Health Organization (WHO)

Tranylcypromine, a monoamine oxidase inhibitor (MAOI), was introduced in 1961 for the treatment of depressive illness. By 1964 its use had been associated with transient hypertensive crises and other adverse effects when taken together with certain cheeses and other foods containing tyramine. This led to the withdrawal of the drug in several countries and the suspension of marketing on a worldwide basis by the major manufacturer pending review of these adverse reactions. Subsequently, in response to requests from the medical profession, tranylcypromine was resubmitted for registration with appropriate warnings in the product information and it is now marketed in more than 30 countries.
