is either (i) a group CH—NP
1A
P
2A
in which P
1A
and P
2A
are each independently hydrogen or a protecting group, or (ii) a carbonyl group; with
18
F
−
to produce the labelled tracer of formula (II) or an amine protected derivative thereof, wherein R
1
is as defined for the compound of formula (I).
