실험 절차

A mixture of 2-bromo-3-pyridinol (commercially available, e.g. from Aldrich) (2.9 g) and potassium carbonate (6.94 g) in DMF (25 ml) was stirred for 20 min before adding 2-(chloromethyl)-4-methylpyridine hydrochloride (for preparation see WO 2008/141011) (3 g). This was stirred at room temperature overnight. The reaction mixture was poured into ice/water and the solid formed was collected by filtration, washed with hexane and dried to give the title compound, 2.87 g (61%).
