Procedure
The title compound (3571 mg, 77%) was prepared from 2-(5-bromopyridin-2-yl)ethanol (Compound 6, Preparation 4) (3.0 g, 14.9 mmol) by a procedure analogous to that described for the preparation of 2-bromo-5-(2-iodoethyl)pyridine in Preparation 2, Step 1. MS (LCMS) m/z 312.0 (M+1). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 3.24-3.36 (m, 2H) 3.41-3.56 (m, 2H) 7.06 (d, J=8.20 Hz, 1H) 7.74 (dd, J=8.20, 2.34 Hz, 1H) 8.60 (d, J=2.34 Hz, 1H).
