are as defined herein, which are useful as inhibitors of PKC-theta and are thus useful for treating a variety of diseases and disorders that are mediated or sustained through the activity of PKC-theta, including immunological disorders and type II diabetes. This invention also relates to pharmaceutical compositions comprising these compounds, methods of using these compounds in the treatment of various diseases and disorders, processes for preparing these compounds and intermediates useful in these processes.
The present invention provides a process for preparing a heterocyclic aldehyde by oxidizing a heterocyclic alcohol with high selectivity and high yield. Specifically, the heterocyclic aldehyde is prepared by reacting a heterocyclic compound having at least one hydroxymethyl group bonded to a carbon atom of a heterocyclic ring with a hypohalogenous acid salt in the presence of a base to oxidize the hydroxymethyl group, wherein reaction is conducted in the co-presence of a 2,2,6,6-tetramethylpiperidine-1-oxyl derivative having at least two 2,2,6,6-tetramethylpiperidine-1-oxyl-4-yl groups.

such as type 2 diabetes and obesity. 11β‐Hydroxysteroid dehydrogenasetype1 (11β‐HSD1) catalyses the intracellular conversion of inactive cortisone to cortisol. Selective 11β‐HSD1 inhibitors have shown beneficial effects in various conditions, including diabetes, dyslipidemia and obesity. A series of adamantylethanonepyridylderivatives has been identified, providing potent and selective inhibitors

Provided is a compound which is useful as an active ingredient for a pharmaceutical having a PKCθ inhibition activity, particularly a pharmaceutical composition for inhibiting acute rejection occurring in transplantation. The present inventors have conducted extensive studies on a compound having a PKCθ inhibition activity, and as a result, they have found that a compound having a structure such as aralkyl and the like on an amino group at the 2-position and also having a structure such as an adamantylalkyl group and the like on an amino group at the 4-position of 2,4-diaminopyrimidine, or a salt thereof has an excellent PKCθ inhibition activity, thereby completing the present invention. The 2,4-diaminopyrimidine compound of the present invention can be used as a PKCθ inhibitor or an inhibitor of acute rejection occurring in transplantation.
