I am having some trouble keeping up with current IUPAC rules.
My understanding is that this would be 1-methoxy-3-phenylpropan-2-amine under current IUPAC recommendations.
However. it is not uncommon to see this written as 1-methoxy-3-phenyl-2-propylamine.
-2-propylamine" (in the above context) ever recommended by IUPAC (i.e. when the blue book was first published) or is this something which is just accepted when it is used incorrectly.
