Procedure
Substituting 33% w/w dimethylamine in ethanol (15 ml) for morpholine and 4-chloro-5-bromo-2-hydroxymethylpyridine (5 g) for 3,4-dichloro-2-hydroxymethylpyridine and using corresponding molar proportions of the other reagents in the method of Example 3D gave after chromatography (silica, chloroform:methanol, 98:2) 4-dimethylamino-5-bromo-2-hydroxymethylpyridine, 3.62 g, as an oil.
