    摘要: The present invention provides a novel process for making compounds of formula 2a or 2b or pharmaceutically acceptable salts thereof, ##STR1## wherein R1 is selected from the group consisting of phenyl and phenyl substituted with at least one group selected from NO.sub.2 and halogen; R.sub.2 is H; R.sub.3 is selected from the group consisting of C.sub.1-4 alkyl, phenyl, and benzyl; and, R.sub.4 is selected from the group consisting of H and halogen; which comprises the steps of: a) oxidizing a racemate of formula 2 or a salt thereof to form a dehydro-compound of formula 3, ##STR2## wherein R.sub.5 is selected from the group consisting of H, CH.sub.3, benzyl, C.sub.2-8 acyl Na, Li and K; and, b) asymmetrically hydrogenating a compound of formula 3 in the presence of a chiral phosphine catalyst to form a compound of formula 2a or 2b.

    摘要: An improved synthesis of a class of inhibitor of Focal Adhesion Kinase (FAK) is provided, wherein use of an expensive palladium-based catalyst is reduced and reaction yields and product purities are improved. Two key reactions of coupling of aryl halides with anilines are optimized with the surprising discovery that the palladium-based catalyst can be dispensed with entirely in one of the reactions. The invention also provides the use of the FAK-inhibitory compounds in the treatment of inflammatory and immune disorders and of arthritis.
