Participants

Reaction Steps

In a reactor, 5 g of the compound obtained in Step C and 2 g of sodium acetate are introduced into ethanol. The mixture is stirred, 2.3 g of acetic anhydride are then added, the reaction mixture is heated to reflux and 20 ml of water are added. The reaction mixture is allowed to return to ambient temperature and the precipitate obtained is filtered off, washed with an ethanol/water 35/65 mixture to yield the title product in a yield of 80% with a chemical purity of 99%.
