反応手順
Phenylglyoxal monohydrate (304 mg, 2 mM) and ethylbenzene (0.49 ml, 4 mM) were dissolved in dichloroethane (4 ml), titanium tetrachloride (0.33 ml, 3 mM) was added, and reacted at room temperature for 2 hours. The reaction mixture was extracted with ethylacetate, the extract was washed with saturated sodium hydrogen carbonate solution and brine, dried with sodium sulfate anhydrous, and then concentrated to obtain a yellow-colored oil. The oil was crystallized from a petroleum ether/diethylether to obtain 357.1 mg (74.0% yield) of 4'-ethylbenzoin.
