Hydrochloric Acid → HCID 15858886, compound

Participants

Reaction Steps

A solution of 0.42 g (1.57 mmol) of the amine obtained in Step C in 5 ml of anhydrous pyridine is cooled to 0° C.; 0.18 ml (1.97 mmol) of acetic anhydride is then added to the medium. After 30 minutes of stirring under argon, the medium is diluted with dichloromethane and then adjusted to an acid pH with a 1N hydrochloric acid solution. The aqueous phase is extracted with dichloromethane; the organic phase is then washed with a saturated solution of sodium hydrogen carbonate. The residue obtained, after evaporation of the solvent in vacuo, is purified on a silica column (eluant: AcOEt/PE: 70/30) to yield the title amide in the form of a white solid.
