Reaction Steps

2-(3,5-Dichloro-pyridin-4-yl)-1-[2-(1-hydroxymethyl-cyclopropyl)-8-methoxy-[1,2,4]triazolo[1,5-a]pyridin-5-yl]-ethanone obtained in example 6 (154 mg, 0.38 mmol) was dissolved in DCM (5 mL) and treated with NaHCO3 (127 mg, 1.51 mmol) and Dess-Martin periodinane (321 mg, 0.756 mmol). The suspension was stirred for 30 min at rt and then treated with a 50 mL of a 1:1 mixture of Na2S2O3 (sat., aq.) and NaHCO3 (sat., aq.). The reaction mixture was then extracted with EtOAc (2×25 mL). The combined organic phases were washed with brine and dried over Na2SO4, filtered and concentrated in vacuo. Yield 156 mg of slightly yellow solid, which was used without further purification.
