Procedure

Follow a procedure similar to that of Preparation 2 except use 1,2-cyclohexanedione (1.0099 g, 9.0065 mmol); 2,6-diphenylaniline (2.2258 g, 9.0731 mmol); toluene (22 mL); p-toluenesulfonic acid monohydrate (0.0859 g, 0.4516 mmol); reflux reaction mixture for 2.3 hours; to isolate 3.5678 g of a brown thick oil. Purify the thick oil be chromatography using a Biotage SNAP 50 g KP-Sil column, loading the thick oil with small amount of 4% ethyl acetate/96% hexanes and 100% ethyl acetate and eluting with a gradient of 4-8% ethyl acetate in hexanes to afford after isolation 1.1388 g (37.2%) of the 2-((1,1′:3′,1″-terphenyl)-2′-ylamino)-2-cyclohexen-1-one as a yellow thick oil.
