Molsidomine is an antianginal agent. Molsidomine is an effective therapeutic agents in the treatment of angina pectoris. Molsidomine is a sydnonimine derivative that acts as a heterocyclic direct nitric oxide donor.

ChEBI: 1-ethoxy-N-[3-(4-morpholinyl)-5-oxadiazol-3-iumyl]methanimidate is a member of morpholines.

1.6 parts by volume of ethyl chloroformate is stirred dropwise into a suspension of 1.0 part by weight of 3-morpholinosydnonimine hydrochloride in 5 parts by volume of pyridine, and the mixture is agitated for a while to allow reaction to take place. Pyridine is removed from the reaction mixture by evaporation, and the residue is dissolved in a small amount of water and extracted with chloroform several times. The extract is dehydrated by adding anhydrous magnesium sulfate and subjected to filtration. Chloroform is removed from the filtrate by distillation, crude crystals being obtained. Recrystallization of the crude crystals from toluene gives 0.6 part by weight of 3-morpholino-N-carboethoxysydnonimine having a melting point of 140°- 141°C. Yield 51%.
