Reaction Steps

A mixture of 4-hydrazino-2-methyl-quinolin-8-ol (21 mg, 0.11 mmol) and 4-ethoxy-1,1,1-trifluoro-but-3-en-2-one (16 μL, 0.11 mmol) in ethanol (0.5 mL) was heated to 75° C. for 30 min. The solvent was than removed in vacuo and the residue was redissolved in acetic acid (0.5 mL). After the addition of concentrated H2SO4 (20 μL) and stirring for 1 h at 100° C., the reaction mixture was cooled to room temperature and a mixture of Na2CO3 (0.40 mg, 3.8 mmol) in water (1 mL) was added. The reaction mixture was then concentrated in vacuo and the residue was partitioned between DCM (10 mL) and water (5 mL). The pH of the aqueous layer was adjusted to 10 by the addition of saturated aqueous NH3 solution and the aqueous layer was extracted with DCM (1×320 mL). The combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo to give the title compound. MS (m/z): 294.2 [M+H+].
