Procedure
According to AVV A, (Z-3-(4-ethoxyphenylamino)-but-2-enoic acid methylester (235.3 mg, 1.0 mmol, 1.0 equiv.) was stirred with Cu(OAc)2 (544.9 mg, 3.0 mmol, 3.0 equiv.) into propionitrile (3.0 ml, 41.9 mmol, 41.9 equiv.) for 24 hours at 120° C. The bluish-brown raw product (307.8 mg) was purified by means of column chromatography (silica gel (50 g), pentane/EtOAc 98:2→70:30→0:100), whereby the pure product was obtained in the form of a weak-yellow oil (254.7 mg, 0.88 mmol, 88%).
