The present invention provides novel α-amino acid derivatives of formula (1):
(wherein, R1, R2, R3, R4, X and Y are as defined in the claims) or pharmaceutically acceptable salts, prodrugs or solvates thereof. The derivatives of formula (1) have βARK1 inhibitory activity and are useful for preventing or treating heart failure. Moreover, the derivatives of formula (1) also have antitumor activity, particularly dual inhibitory activity on Aurora kinase and CDK, and are useful for cell proliferative diseases such as cancer.

The solvent-free, palladium-catalysed reaction of anilides with CuCl2 in the presence or absence of copper acetate yields ortho-chlorinated anilides in good to excellent yields, even on a large scale (100 mmol). By contrast, the equivalent reactions with copper bromide, either solvent free or in 1,2-dichloroethane, in the presence or absence of palladium, under air or inert conditions, gave the products
