'diverted' is the definition.
('amuse' can be a synonym of 'divert')

(Other definitions for amused that I've seen before include "Mildly diverted or entertained" , "Pleasantly occupied" , "Queen Victoria wasn't!" , "Delighted" , "Medusa (anag)" .)
'diverted' is the definition.
(sidetracking is a kind of diverting)
This is all the clue.
