Reaction Steps

A mixture of 4-bromo-2,6-dimethyl-pyridine (1 g, 5.4 mmol), 4-bromo-3-fluoro-phenol (0.59 g, 5.4 mmol), and potassium carbonate (0.89 g, 6.4 mmol) in xylenes (2 ml) was heated at 150° C. (oil bath temperature) in a sealed tube for 48 hours. After cooling to room temperature the mixture was diluted with EtOAc and filtered through a diatomaceous earth pad. The filtrate was evaporated till dryness and the crude product thus obtained was purified by column chromatography (silica gel; DCM to DCM/EtOAc up to 10% as eluent). The desired fractions were collected and evaporated in vacuo to yield intermediate 17 (1.18 g, 72%).
