Shandong Amini
Njia ya maandalizi:MgCl2 (22.2g, 233.35mmol) na triethylamine (59.03g, 583.39mmol) ziliongezwa kwenye suluhisho la asetonitrile (200ml) iliyochochewa ya 2-chlorophenol (20.0g, 155.60mmol). Ongeza poli (kitabu cha kemikali formaldehyde, 0.52g, 1.05mol) kwenye mchanganyiko, na kisha reflux kwa saa 4. Mchanganyiko unaosababishwa umepozwa kwa joto la kawaida, ulizimwa na 2nhcl, hutolewa na ether, kavu na MgSO4, kuchujwa na kujilimbikizia chini ya shinikizo la kupunguzwa. Kiwanja ghafi kilisafishwa kwa kromatografia ya safuwima ya jeli ya silika ili kupata kiwanja cha kichwa 3-chloro-2-hydroxybenzene.
