Procedure

To a solution of NaOH (0.2 g, 5 mmol) in 3 mL ethanol were added commercially available 1-(2-isobutoxyphenyl)ethanone (100 mg, 0.52 mmol) and commercially available 3-methyl-1H-indazole-5-carbaldehyde (200 mg, 1.25 mmol). The reaction mixture was stirred at room temperature for 24 h, concentrated under reduced pressure and the product was purified by SiO2 flash chromatography (60:40 hexanes/ethyl acetate) to afford (E)-1-(2-isobutoxyphenyl)-3-(3-methyl-1H-indazol-5-yl)prop-2-en-1-one (50 mg, 28.6%). C21H22N2O2: 335 (MH+).
