Hydrochloric Acid → HCID 10377971, compound

Participants

Reaction Steps

A solution of 0.49 g (2.57 mmol) of the amine obtained in Step B of Example 40 in 10 ml of dichloromethane is cooled to 0° C.; 1 ml (7.7 mmol) of triethylamine and also 0.41 g (3.85 mmol) of butyryl chloride are then added in succession to the medium. After 30 minutes of stirring under an inert atmosphere, the reaction mixture is acidified with a hydrochloric acid solution (1N); the aqueous phase is then extracted with dichloromethane. The organic phase, dried over magnesium sulphate and then filtered, is concentrated in vacuo. Chromatography on a silica column (eluant: PE/AcOEt: 40/60) yields the title amide in the form of a white solid.
