A compound of the formula: ##STR1## wherein R is lower alkyl, may be prepared, for example, by reducing a compound of the formula: ##STR2## wherein R is same as above. Other methods for preparing the compound [I] are also disclosed. The compound [I] and a pharmaceutically acceptable acid addition salt thereof are useful as anti-diabetic agents.
We herein describe the results of further evolution of glycogensynthase kinase (GSK)-3β inhibitors from our promising compounds containing a 2-phenylmorpholine moiety. Transformation of the morpholine moiety into a piperazine moiety resulted in potent GSK-3β inhibitors. SAR studies focused on the phenyl moiety revealed that a 4-fluoro-2-methoxy group afforded potent inhibitory activity toward GSK-3β
