Divert attention from Diane's pamphlet (8)
I believe the answer is:
distract
'divert attention' is the definition.
(I've seen this in another clue)
'diane's pamphlet' is the wordplay.
'diane's' becomes 'di's' (short for Diane).
'pamphlet' becomes 'tract' (synonyms).
'dis'+'tract'='DISTRACT'
'from' is the link.
(Other definitions for distract that I've seen before include "Side track" , "Subject to diversion" , "Put off" , "amuse" , "beguile" .)
