Versuchsvorschrift
Following Step 3 from General Procedure A, tert-butyl 3-bromothiophene-2-carbonyl(4-methoxy-2-methylphenyl)carbamate (14 g, 33 mmol) was reacted with bis(tri-tert-butylphosphine)palladium (750 mg, 1.5 mmol) to afford the desired product (7.0 g, 85%) as a dark brown solid: ESI MS m/z 250 [C12H8FNO2S+H]+.
