(Z)-3-(3-(3,5-bis(trifluoromethyl)phenyl)-1H-1,2,4-triazol-1-yl)acrylic acid (0.250 g, 1.0 eq.) was dissolved in DCM (12 mL). tert-butyl 6-amino-3-azabicyclo[3.1.0]hexane-3-carboxylate (0.17 g, 1.2 eq.) was added and the reaction mixture was cooled to −60° C. T3P (0.51 mL, 1.2 eq.), followed by DIPEA (0.24 mL, 2.0 eq.) was then added at the same temperature. The reaction mixture was stirred for 30 min. and transferred into water (50 mL) and extracted with DCM (2×50 mL). The combined organic layer was washed with brine (50 mL), dried over anhydrous MgSO4, filtered, and concentrated under reduced pressure (25° C., 20 mmHg) to afford crude product, which was purified by chromatography (0-5% MeOH in DCM) to give (Z)-tert-butyl 6-(3-(3-(3,5-bis(trifluoromethyl)phenyl)-1H-1,2,4-triazol-1-yl)acrylamido)-3-azabicyclo[3.1.0]hexane-3-carboxylate (0.28 g; 66.1% yield).
