実験手順
5-(2-Hexyldecyl)-2-thiophenecarboxylic acid (1.00 g, 2.84 mmol., 1.00 equiv.) and CH2Cl2 (5 mL) were added to a 10 mL schlenk flask. The solution was cooled to 0° C. Oxalyl chloride (0.60 mL, 6.5 mmol, 2.3 equiv.) was then added. The ice/water bath was left in place and the solution was stirred for 64 hours while warming to room temperature. The reaction mixture was concentrated to a clear brown liquid (931 mg, 88% yield). 1H NMR (400 MHz, CDCl3) δ 7.84 (d, J=3.9 Hz, 1H), 6.87 (d, J=3.8 Hz, 1H), 2.81 (d, J=6.7, 2H), 1.68 (b, 1H), 1.34-1.19 (m, 24H), 0.93-0.85 (m, 6H).
