Procedure

tert-Butyl (S)-1-((R)-1-(3-(7-(ethylthio)quinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)-2,2,2-trifluoroethyl)pyrrolidin-3-ylcarbamate (95 mg, 0.17 mmol) was stirred in TFA for 30 minutes. The reaction was concentrated to dryness, then diluted in 1 mL of methanol and added dropwise into 4N HCl in ether. The resulting precipitate was filtered and dried under vacuum to yield (S)-1-((R)-1-(3-(7-(ethylthio)quinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)-2,2,2-trifluoroethyl)pyrrolidin-3-amine (56 mg, 71% yield) hydrochloride as a solid. LCMS APCI (+) m/z 473 (M).
