Procedure

500 g (6.32 mol) of pyridine and subsequently 600 g (5.88 mol) of acetic anhydride were added dropwise while stirring to the crude (R)-(1-hydroxyethyl) ferrocene from Example 1 at 25° C. under argon. The reaction mixture was allowed to stand for a further 20 hours at 25° C., then hydrolysed with 1.5 l of ammonium chloride solution (20%) and extracted three times with 1.5 l each time of ethyl acetate. The solvent was distilled off from the combined organic phases.
