The present invention relates to novel compounds of formula (I) that are capable of inhibiting one or more kinases, especially SYK (Spleen Tyrosine Kinase), LRRK2 (Leucine-rich repeat kinase 2) and/or MYLK (Myosin light chain kinase) or mutants thereof. The compounds find applications in the treatment of a variety of diseases. These diseases include autoimmune diseases, inflammatory diseases, bone diseases, metabolic diseases, neurological and neurodegenerative diseases, cancer, cardiovascular diseases, allergies, asthma, alzheimer's disease, parkinson's disease, skin disorders, eye diseases, infectious diseases and hormone-related diseases.
The object of the present invention is to provide a compound and a pharmaceutical composition having excellent Syk inhibitory activity. According to the present invention, a nicotinamide derivative represented by the following formula (I) or a salt thereof is provided,
wherein
R
1
is a substituent represented by the following formula (II-1), (III-1), or (IV-1)
(wherein R
3
, R
4
, R
5
, n, and X
1
have the same definitions as those described in the specification), and R
2
is a pyridyl, indazolyl, phenyl, pyrazolopyridyl, benzisoxazolyl, pyrimidinyl, or quinolyl group, each of which optionally has at least one substituent.

selectivity and good functional group tolerance, and uses commercially available catalyst components and reagents [CuOAc, 2,2′-bis(oxazoline) ligand, (trimethylsilyl)isocyanate, and N-fluorobenzenesulfonimide]. The isocyanate products may be used without isolation or purification in a subsequent coupling step with primary and secondary amines to afford hundreds of diverse ureas. These results provide
