Procedure

To the solution of (Z)-3-(3-(3,5-bis(trifluoromethyl)phenyl)-1H-1,2,4-triazol-1-yl)acrylic acid (0.2 g, 0.569 mmol) and 2-(3,5-dimethylmorpholino)acetohydrazide (0.106 g, 0.569 mmol) in THF (10 mL) were added T3P (0.543 g, 0.854 mmol) followed by DIPEA (0.110 g, 0.854 mmol) at −60° C. and stirred for 2 h. The reaction mixture was transferred into 25 mL iced-water and extracted with ethyl acetate (2×25 mL) and the combined organic layers was washed with brine, dried over anhydrous sodium sulphate, and concentrated under reduced pressure to afford the crude product, which was purified by chromatography (0-3% MeOH/CH2Cl2) to give 0.02 g of (Z)-3-(3-(3,5-bis(trifluoromethyl)phenyl)-1H-1,2,4-triazol-1-yl)-N′-(2-(3,5-dimethylmorpholino)acetyl)acrylohydrazide (Yield: 7%). 1H NMR (400 MHz, DMSO-d6) δ 10.58 (s, 1H), 9.83 (s, 1H), 9.56 (s, 1H), 8.54-8.56 (m, 2H), 8.25-8.30 (m, 1H), 7.49-7.51 (d, J=10.4 Hz, 1H)), 6.01-6.04 (d, J=10.4 Hz, 1H), 3.44-3.57 (m, 2H), 3.28-3.34 (m, 2H), 3.21 (s, 1H), 3.15 (s, 1H), 2.84-2.88 (m, 2H), 0.93-1.04 (m, 6H): LCMS m/z 521.18 [M+H]+, tR 1.898 min.
