Five portions of 4-bromobutanoylchloride (0.35 ml×5) and potassium carbonate (0.4 g×5) were added in 24 hours to a solution of hydrocortisone (1 g) in CHCl3 dried over P2O5 and stirred for 5 days. The solution was treated with water, the organic phase was separated, dried (Na2SO4) and deprived of the solvent at reduced pressure.
