The present application relates to a process for preparing unsymmetric secondary tert-butylamines which, as well as the tert-butyl radical, also comprise an alkyl, cycloalkyl or benzyl radical. They are prepared by reacting corresponding aldehydes with tert-butylamine and hydrogen in the presence of hydrogenation catalysts (reductive amination) in the liquid phase.
The present invention provides for a method for treating a disease condition associated with PI3-kinase a and/or a receptor tyrosine kinase (RTK) in a subject. In another aspect, the invention provides for a method for treating a disease condition associated with PI3-kinase α and/or an RTK in a subject. In yet another aspect, a method of inhibiting phosphorylation of Akt (S473) in a cell is set forth.
