Procedure

To a solution of 5-(2,3-dihydro-benzo[1,4]dioxin-6-yl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (0.4 g, 1.5 mmol) in dichloromethane (20 mL), triethylamine (0.62 mL, 4.47 mmol) and chloroacetyl chloride (0.142 mL, 1.8 mmol) were added successively. The mixture was then stirred overnight. Water was added and the mixture was extracted with dichloromethane, dried over magnesium sulphate and concentrated under reduced pressure. The crude was used without further purification. Yield: 0.52 g, 100%; LCMS Method: 2: 3.57 min, 345-347 [M+1].
