Reaction Steps

tert-butyl 2-(3-(6-(5-(N-tert-butylsulfamoyl)pyridin-3-yl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl)ureido)ethylcarbamate (35 mg) was suspended in HCl (4M in dioxane, 2 mL) and DCM (2 mL) and the reaction mixture stirred overnight at room temperature. After this time the reaction mixture was pippetted slowly onto diethyl ether at −78° C. and maintained at this temperature for 20 minutes. The resultant white solid was filtered, washed with further diethyl ether and dried under vacuum to afford the title compound (21 mg).
