Procedure

A solution of (3S)-1-(1-(3-(8-(cyclopropylmethoxy)quinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)-2,2,2-trifluoroethyl)pyrrolidin-3-amine (Example 5; 0.15 g, 0.27 mmol), DIEA (0.14 mL, 0.81 mmol) and acetic anhydride (0.038 mL, 0.41 mmol) in dichloromethane (4 mL) was stirred at ambient temperature for 18 hours. The mixture was partitioned between ethyl acetate (15 mL) and water (5 mL). The organic layer was separated and washed with aqueous 1N HCl (5 mL), water and brine, then dried (MgSO4), filtered and concentrated under reduced pressure to afford N-((3S)-1-(1-(3-(8-(cyclopropylmethoxy)quinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)-2,2,2-trifluoroethyl)pyrrolidin-3-yl)acetamide (0.076 g, 54%). LCMS APCI (+) m/z 525 (M+H).
