Procedure

A solution of N-(1,5-dimethyl-1H-pyrazol-3-yl)-3-{[2-fluoro-1-(fluoromethyl)ethyl]oxy}-5-hydroxybenzamide (0.61 mmol) in acetonitrile (5 mL), was treated with the potassium carbonate (1.23 mmol) and 5-(azetidin-1-ylcarbonyl)-2,3-dichloropyridine (0.68 mmol), before being heated to 120° C. in a microwave reactor for 4 hours. The mixture was filtered and evaporated in vacuo before being chromatographed on silica, eluting with 0-5% methanol in ethyl acetate, to give the desired compound as a white foam (175 mg).
