Compounds and methods for preparing substituted 3-(1-amino-2-methylpentane-3-yl)phenyl compounds from an isomerically pure starting material are described. In particular, methods of preparing a 3-(1-(dimethylamino)-2-methylpentane-3-yl)phenol as a substantially optically pure (R,R) stereoisomer are described. Using a method of the present invention, only the (R,R) and (S,S) stereoisomers of the target compound are produced, increasing the yield and stereoselectivity of the desired (R,R) stereoisomer.
