[Title <strong>of</strong> the Invention]<br />

16α-substitution pregnen group, and an intermediate <strong>for</strong> manufacturing the 16α-substitution<br />

pregnen group<br />

[Claims]<br />

1. A steroid compound indicated by Formula [I]<br />

[In this <strong>for</strong>mula, R 1 means phenyl or naphthyl.]<br />

2. A steroid compound indicated by Formula [II]<br />

[In this <strong>for</strong>mula, R 1 means a phenyl or naphthyl.]<br />

[Excerpt <strong>of</strong> Detailed Description <strong>of</strong> the Invention]<br />

This invention relates to a 16α-substitution pregnen group useful as an anti-inflammatory<br />

drug and an intermediate useful <strong>for</strong> manufacturing this 16α-substitution pregnen group. The<br />

steroid compound indicated by Formula [I], which has anti-inflammatory properties, is easily<br />

manufactured by treating the steroid intermediate indicated by Formula [II].<br />

[Explanation]<br />

It is recognized that the main use <strong>of</strong> a compound <strong>of</strong> the related invention (Claim 2) is a raw<br />

material (an intermediate) <strong>of</strong> a compound (a final compound) <strong>of</strong> the specified invention (Claim 1).<br />

There<strong>for</strong>e it is highly appropriate that the art <strong>of</strong> the technical field <strong>of</strong> a compound <strong>of</strong> the related<br />

invention is applied to the technical field <strong>of</strong> a compound <strong>of</strong> the specified invention. The technical<br />

fields <strong>of</strong> both inventions are technically and directly associated with each other and their<br />

industrial fields <strong>of</strong> application <strong>of</strong> them are the same.<br />

In addition, both compounds have common fundamental structures<br />

and the final compound indicated by Formula [I] is directly manufactured from an intermediate<br />

indicated by Formula [II]. There<strong>for</strong>e, it is recognized that both compounds are closely and<br />

technically associated with each other, and the substantial parts <strong>of</strong> matters in the claims <strong>of</strong> both<br />
