200 mg | In ethanol; for 3h;Reflux; | 200 mg of <strong>[6971-45-5]2-methoxyphenylhydrazine hydrochloride</strong> was dissolved in 4 ml of ethanol and 134 mul of 3-methyl-2,4-pentanedione was added, followed by heating to reflux for 3 hours. To the reaction mixture was added 50 ml of water, followed by neutralizing with a saturated aqueous sodium carbonate solution and extracting with 60 ml of ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate and subsequently the solvent was distilled off under reduced pressure to afford 209.8 mg of the title compound. 1H-NMR (CDCl3); delta (ppm) 1.98 (3H, s), 2.02 (3H, s), 2.24 (3H, s), 3.80 (3H, s), 6.99-7.04 (2H, m), 7.29-7.31 (1H, m), 7.34-7.39 (1H, m).
