    I raro i te whakamarumaru o te hau inert, 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium catalyst (2 mol %) me te biquinoline (bq, 3 mol %) i marara ki roto i te whakarewa waro (2 mL) ), katahi Ka tāpirihia te H2O (2 mmol), ka hiki te mahana ki te 80°C mō te 6 hāora. Katahi ka tangohia te wairewa tauhohenga e toru nga wa ki te Et2O (5 mL), ka whakakotahihia nga wahanga waro, ka whakamaroke-maroke te whakarewa i raro i te pehanga iti. Ko te hua masivesivá i riro i raro i te chromatography tīwae i runga i te tīwae silica gel (300-400 mata), a ko nga eluent he petroleum ether , ki te tiki i te hua ūnga 2-methylbenzophenone. Ngā āhuatanga matū Korekore he tae, he kowhai marama he wai maramara. Ko te ira whakarewa he 134°C. Whakamahia hei takawaenga rongoa.
