Abstract:
The present invention provides a oxazole compound represented by Formula (1), or a salt thereof: wherein R 1  is an aryl group which may have one or more substituents; R 2  is an aryl group or a nitrogen atom-containing heterocyclic group each of which may have one or more substituents; and W is a divalent group represented by —Y 1 -A 1 - or —Y 2 —C(═O)— wherein Y 1  is a group such as —C(═O)—, A 1  is a group such as a lower alkylene group, and Y 2  is a group such as a piperazinediyl group. The oxazole compound has a specific inhibitory action against phosphodiesterase 4.

Claim (Index 21):
The method of  claim 18 , wherein R 1  is a phenyl group having two substituents selected from the following (1-2), (1-3), (1-4) and (1-5):\n (1-2) unsubstituted or halogen-substituted lower alkoxy groups, (1-3) lower alkenyloxy groups, (1-4) lower alkynyloxy groups, and (1-5) cyclo C 3-8  alkyl lower alkoxy groups; R 2  is a phenyl group or a pyridyl group each of which may have 1 to 2 substituents selected from the following (2-2), (2-3), (2-4) and (2-5): (2-2) unsubstituted or halogen-substituted lower alkoxy groups, (2-3) unsubstituted or halogen-substituted lower alkyl groups, (2-4) lower alkenyloxy groups, and (2-5) halogen atoms; and W is a divalent group represented by Formula (i):\n \u2014Y 1 -A 1 -\u2003\u2003Formula (i) \n wherein A 1  is a lower alkylene group, and Y 1  is \u2014C(\u2550O)\u2014 or \u2014C(\u2550O)\u2014N(R 3 )\u2014 wherein R 3  is a hydrogen atom.
