Procedure

3-{[6-(Azetidin-1-ylcarbonyl)pyridin-3-yl]oxy}-N-(5-methylpyrazin-2-yl)-5-[(phenylmethyl)oxy]benzamide (3.9 g, 7.9 mmol) was dissolved in ethyl acetate (200 mL) and ethanol (200 mL) then 10% palladium on charcoal added. The reaction was stirred under an atmosphere of hydrogen for 16 hours. Methanol (150 mL) was added to aid solubilisation of the material and the suspension filtered, the residue taken up in DMF, filtered and the combined filtrates evaporated to dryness to give the desired material (3.17 g). 1H NMR δ (d6-DMSO): 2.33 (quin, 2H), 2.53 (s, 3H), 4.13 (t, 2H), 4.64 (t, 2H), 6.81 (s, 1H), 7.31 (s, 1H), 7.34 (s, 1H), 7.62 (d, 1H), 8.05 (d, 1H), 8.40 (s, 1H), 8.47 (s, 1H), 9.26 (s, 1H), 10.35 (s, 1H), 11.02 (s, 1H); m/z 406 (M+H)+
