A reliable route is described for the preparation of various 2-substituted derivatives of [1,2,3,4,4a,8a-13 C 6 ]-naphthalene via the bromide 10. The approach is used to prepare [naphthalene-1,2,3,4,4a,8a-13 C 6 ]-2-(2-bromoethyl)naphthalene (1), a key intermediate in the synthesis of labelled SR577
