is an optionally substituted aliphatic or heteroaliphatic chain L
1
is a covalent bond or a linker atom or group; Cy
1
is a hydrogen atom or an optionally substituted cycloaliphatic, polycycloaliphatic, heterocycloaliphatic, polyheterocycloaliphatic, aromatic or heteroaromatic group; Ar is an optionally substituted aromatic or heteroaromatic group; and the remaining substituents are defined in the specification. The compounds are potent and selective inhibitors of p38 kinase and are of use in the prophylaxis and treatment of immune or inflammatory disorders.

A facile and efficient synthesis of fully substituted pyridin-2(1H)-ones has been developed by the reaction of readily available alpha-oxoketene-S,S-acetals with malononitrile in the presence of sodium methoxide in methanol under reflux. (C) 2011 Elsevier Ltd. All rights reserved.
