YieldReaction ConditionsOperation in experiment
81% at 65℃; for 6 h; In a 50 mL reaction flask 3-bromophenylhydrazine 2 (1.40 g, 7.5 mmol) was added,Acetylacetone 3a (1.00 g, 10.0 mmol) and 10 mL of ethanol were added and the reaction was stirred at 65 ° C for 6 hours. anti- At the end of this time, the mixture was allowed to cool to room temperature, the volatile components were removed under reduced pressure and the residue was purified by silica gel column Chromatography (eluent petroleum ether (60-90 ° C) / ethyl acetate, v / v = 30: 1) gave To a yellow liquid product 4a (1.52 g, yield 81percent). The target product passes the nuclear magnetic resonance spectrum Confirmed.
