90.0 mmol, 3.00 eq) in toluene (60 mL) and water (0.1 mL)
was purged with argon. Subsequently, benzamide (4.36 g,
36.0 mmol, 1.20 eq) and 3,3′‐dibromo‐2,2′‐bithiophene 11
(9.72 g, 30.0 mmol) were added and the reaction mixture
was heated at 110°C for 2 days. After cooling to room tem-
perature, the crude product was purified via column chroma-
tography (petroleum ether : dichloromethane = 3:1) to yield
DTP 1 as a white crystalline solid (3.19 g, 17.8 mmol,
59%). The analytical data of DTP 1 were in accordance with
the data above and with literature.[21]

A suspension of CuI (114 mg, 0.60 mmol, 0.20 eq), DMEDA
(0.27 mL, 2.40 mmol, 0.80 eq), K2CO3 (1.24 g, 9.00 mmol,
3.00 eq), 4‐nitrobenzamide (748 mg, 4.50 mmol, 1.50 eq),
and 3,3′‐dibromo‐2,2′‐bithiophene 11 (972 mg, 3.00 mmol)
in toluene (6 mL) was degassed and heated at 110°C for
2 days. After cooling to room temperature, the suspension
was filtered through a plug of celite and the residue was
washed with dichloromethane. The raw product was purified
via column chromatography (petroleum ether : dichlorometh-
ane = 3:1) to give 1 as a white solid (211 mg, 1.18 mmol,
39%) and 4‐(p‐nitrobenzoyl)‐4H‐dithieno[3,2‐b:2′,3′‐d]pyr-
role 15 as a yellow solid (90.1 mg, 0.27 mmol, 9%). Mp:

A suspension of 3,3′‐dibromo‐2,2′‐bithiophene 11 (162 mg,
0.50 mmol), NaOtBu (144 mg, 1.50 mmol, 3.00 eq),
Pd2(dba)3 (22.9 mg, 0.03 mmol, 0.05 eq), tri‐tert‐
butylphosphine (20.6 mg, 0.10 mmol, 0.20 eq), and
triphenylsilylamine (165 mg, 0.60 mmol, 1.20 eq) in toluene
(1.2 mL) was purged with argon and heated at 80°C over-
night. After purification via column chromatography (petro-
leum ether : dichloromethane = 3:1), 1 was afforded as a
white crystalline solid (64.2 mg, 0.36 mmol, 72%). The ana-
lytical data of DTP 1 were in accordance with the data above
and with literature.[21] The side product tert‐
butoxytriphenylsilane was obtained as a white solid and the
analytical data were in accordance with the literature.[45]
