The present invention is directed to a method of use of triazolo-pyridazine compounds in the treatment of neuropathic pain. The present invention is also directed to the use of triazolo-pyridazine compounds in the treatment of psychiatric and mood disorders such as, for example, schizophrenia, anxiety, depression, bipolar disorders, and panic, as well as in the treatment of pain, Parkinson’s disease, cognitive dysfunction, epilepsy, circadian rhythm and sleep disorders - such as shift-work induced sleep disorder and jet-lag, drug addiction, drug abuse, drug withdrawal and other diseases. The present invention is also directed to novel triazolo-pyridazine compounds that selectively bind to α2δ-1 subunit of Ca channels.

Optimization of the kineticresolution of 2-amino-4-phenyl-butane was achieved at 80 °C using CAL-B-catalyzed aminolysis of carboxylic acids and their ethyl esters. The reactions carried out with long chain esters and the corresponding acids as acyldonors proceeded with remarkably high enantioselectivity. The use of carboxylic acids as acylating agents led to a marked acceleration of the reaction
