Reach out during break in European capital (9)
I believe the answer is:
bucharest
'european capital' is the definition.
(capital of Romania)
'reach out during break' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'during' is an insertion indicator.
'break' becomes 'bust' (busting is a kind of breaking).
'reach' is an anagram of 'chare'.
'chare' placed within 'bust' is 'BUCHAREST'.
'in' is the link.
(Other definitions for bucharest that I've seen before include "European capital" , "Romanian capital" , "Balkan city" , "European city" , "Capital of Romania" .)
