To a solution of (S)-tert-butyl 1-(5-fluoropyrimidin-2-yl)-6-methyl-6,7-dihydro-1H-[1,2,3]triazolo[4,5-c]pyridine-5(4H)-carboxylate (0.711 g, 2.13 mmol) in CH2Cl2 (10 mL) was added 4M HCl in dioxane (2.66 mL, 10.6 mmol). After stirring overnight at rt, the reaction was concentrated in vacuo to give the desired product as a light yellow solid (0.580 mg, 100%). MS (ESI) mass calcd.
