Compounds of formula (1.0.0) are described, as well as the usefulness of a pharmaceutical composition for treating inflammatory, respiratory and allergic diseases and conditions, especially asthma; chronic obstructive pulmonary disease (COPD) including chronic bronchitis, emphysema, and bronchiectasis; chronic rhinitis; and chronic sinusitis.
The present invention relates to a compound represented by Formula (I):
(wherein Ar
1
represents an imidazolyl group which may be substituted with 1 to 3 substituents; Ar
2
represents a pyridinyl group, a pyrimidinyl group, or a phenyl group which may be substituted with 1 to 3 substituents; X
1
represents (1) —C≡C— or (2) a double bond etc. which may be substituted; R
1
and R
2
represent, for example, a C1-6 alkyl group or C3-8 cycloalkyl group which may be substituted)
or a pharmacologically acceptable salt thereof and to the use thereof as pharmaceutical agents. The object of the present invention is to find a therapeutic or preventive agent for diseases caused by Aβ. According to the present invention, a therapeutic or preventive agents for diseases caused by Aβ can be provided.

The present invention provides compounds for modulating protein kinase enzymatic activity for modulating cellular activities such as proliferation, differentiation, programmed cell death, migration and chemoinvasion. Compounds of the invention inhibit, regulate and/or modulate kinases, particularly Raf. Methods of using the compounds and pharmaceutical compositions thereof to treat kinase-dependent diseases and conditions are also an aspect of the invention.
The present invention relates to a process for preparing a compound of formula (6a):
wherein Ar
1
represents an imidazolyl group which may be substituted with 1 to 3 substituents shown below; Ar
2
represents a pyridinyl group, a pyrimidinyl group or a phenyl group which may be substituted with 1 to 3 substituents; and R
11
represents a group selected from certain substituents.
