methyl 3-phenylamino-2-propenoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: According to AVV A, 3-phenylamino acrylic acid methylester (177.2 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 19 hours at 120° C. The orange-brown oily raw product (191.2 mg) was purified by means of column chromatography (silica gel (50 g), pentane/EtOAc 98:2→0:100), whereby the pure product was obtained in the form of a white solid (37.2 mg, 0.16 mmol, 16%). The orange-brown oily raw product (191.2 mg) was purified by means of column chromatography (silica gel (50 g), pentane/EtOAc 98:2→0:100), whereby the pure product

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: According to AVV A, 3-phenylamino acrylic acid methylester (197) (177.2 mg, 1.0 mmol, 1.0 equiv.) was stirred with Cu(OAc)2 (544.9 mg, 3.0 mmol, 3.0 equiv.) into acetonitrile (3.0 ml, 57.1 mmol, 57.1 equiv.) for 22 hours at 110° C. The greenish solid obtained as raw product (242.4 mg) was purified by means of column chromatography (silica gel (50 g), pentane/MTBE 95:5→0:100, then MTBE/EtOAc 100:0→0:100), whereby the desired product was obtained in the form of a yellowish solid (35.1 mg, 0.16 mmol, 16%). The greenish solid obtained as raw product (242.4 mg) was purified by means of column chromatography (silica gel (50 g), pentane/MTBE 95:5→0:100

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
