Transamination of 2-piperidinochromanes with (het)arylamines as a convenient route to 2-(het)arylaminochromanes

Reaction between 2-piperidinochromane and (hetero)aromatic amines in the presence of pyridinium tosylate affords the products of replacement of the piperidine fragment by the (hetero)arylamino moiety in good yields. This single-stage process opens facile and efficient way to the functionalized N-arylchroman-2-amines.
