Reaction Steps

The title compound is prepared from 6-methoxy-3-pyridinecarboxaldehyde (0.5 g, Aldrich) by a sequence of standard transformations consisting of Wittig reaction with (carbethoxymethylene)triphenylphosphorane and NaOH, catalytic hydrogenation of the exocyclic C—C double bond, reduction to the corresponding alcohol with LiAlH4, and conversion to the bromide using N-bromosuccinimide and PPh3.
