Reaction Steps

In a 50 ml round-bottomed flask, 0.0025 mol of the compound obtained in Step E is dissolved in 5 ml of pyridine. The solution is cooled with the aid of an ice bath and 5 ml of acetic anhydride are added dropwise. Stirring is carried out for 5 hours at ambient temperature. The reaction mixture is poured into aqueous 3M hydrochloric acid solution and is then extracted with ethyl ether. The organic phase is washed with aqueous 10% potassium carbonate solution and then with water, is dried over magnesium sulphate and is evaporated under reduced pressure. The residue obtained is recrystallised.
