ビタミンD!(N。Furthermore, it has recently been found that in addition to the so-called vitamin D activity, it also has a differentiation-inducing effect. However, when conventional active vitamin D3 is used as an anticancer agent based on its differentiation-inducing effect, its vitamin D activity becomes a side effect. Therefore, with the aim of separating these effects, research has been conducted on active vitamin D derivatives that do not have vitamin D activity and their synthesis methods. ! (N.

It is further protected with another protecting group to obtain a compound of formula (■). In this case, the protecting group is a group that is stable to the alkali metal aluminum hydride or alkali metal borohydride used in the next step, such as a tetrahydropyranyl group, benzyl group, monomethoxymethyl group, etc. used. This step is preferably carried out by treating with dihydropyran in the presence of pyridinium para-toluene sulfonate (hereinafter abbreviated as PPTS) to protect the 17-position hydroxyl group as tetrahydropyranyl ether.
