Procedure
The hydroxymethyl compound obtained above was converted to 2-chloromethyl-4-methoxypyridine by the method of Part (iv), above, to provide 0.895 g (5.68 mmole). This was reacted with an equimolar amount of triphenylphosphine in toluene (10 ml) at reflux for 20 hours. The precipitated product was filtered to give 860 mg of the title compound as a yellow solid.
