実験手順
To a solution of (E)-4-amino-4-ethoxy-1,1,1-trifluorobut-3-en-2-one, (Compound [XXIV]) (7.00 g, 38.2 mmol, 1.0 eq.) in ethanol (150 mL) in a 250 mL round bottom flask was added hydrazine hydrochloride (2.75 g, 40.16 mmol, 1.05 eq.) followed by triethylamine (4.05 g, 40.16 mmol, 1.05 eq.). The reaction mixture was heated to reflux for 16 hours. After cooling and concentration, the residue was purified by silica gel chromatography using CHCl3-MeOH (10%) as the eluant to give Compound [XXV]: LCMS m/e 152 (M+H); 1H NMR (400 MHz, DMSO-d6) δ ppm 5.32 (s, 2H) 5.51 (s, 1H) 12.12 (br. s., 1H).
