A process for producing a 23-hydroxy-24-oxovitamin D3 derivative which comprises oxidizing a 24-hydroxyvitamin D3, derivative to form a 24-oxovitamin D3 derivative, silyl-enol-ethyerifying the 24-oxovitamin D3 derivative to form an etherified compound, oxidizing the etherified compound, and subjecting the resulting compound to a hydroxyl-protecting group elimination reaction.
