Hydrochloric Acid → HCID 18399743, compound

Participants

Reaction Steps

15 ml of a 2.9N ethanolic HCl solution are added to a solution of 0.9 g of the compound obtained in Step 3 in 15 ml of ethanol. The reaction mixture is stirred for 24 hours at ambient temperature and then concentrated in vacuo, enabling the expected product to be isolated in dihydrochloride form. The dihydrochloride is converted into a free base by extraction in dichloromethane in the presence of water that has previously been adjusted to a basic pH by 20% sodium hydroxide solution.
