実験手順

Pd(PPh3)4 (61 mg, 0.053 mmol) was added to a degassed solution of 2,6-bis(tri-n-butylstannyl)-benzo[1,2-b:4,5-b′]dithiophene (202 mg, 0.26 mmol) and 2-[4-Bromo-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazol-2-yl]-pyrrolidine-1-carboxylic acid tert-butyl ester (260 mg, 0.58 mmol) in toluene (4 mL). The reaction was refluxed for 24 hours, then cooled to room temperature and filtered through CELITE and a palladium scavenging column (Stratospheres™ PL-Guanidine MP SPE+, Part #: PL3514-CM89). The solids were rinsed twice with toluene. The filtrate was concentrated and the crude product purified by flash chromatography to yield the desired, fully protected product (100 mg, 41%). LCMS-ESI+: calculated for C46H68N6O6S2Si2: 920.42; observed [M+1]+: 921.45.
