5) The acetylation of 20(S)-(3-hydroxy-3-methylbutoxy)pregna-5,7-diene-1alpha,3beta-diol (XXI) with acetic anhydride and dimethylaminopyridine (DMAP) in pyridine gives the 1alpha,3beta-diacetoxy derivative (XXII), which was submitted to UV irradiation with a 400 W high-pressure mercury lamp in THF yielding the corresponding 22-oxavitamin D3 derivative (XXIII). Finally, this compound is deacetylated by a treatment with KOH in methanol.
