5-Phenethylthiophene-2-carbaldehyde was synthesized from 5-(phenylethynyl)thiophene-2-carbaldehyde (4.0 g, 18.8 mmol) following the conditions used to hydrogenate 4-(phenylethynyl)thiophene-2-carbaldehyde to 4-phenethylthiophene-2-carbaldehyde (Example 1.1.b). 5-Phenethylthiophene-2-carbaldehyde (3.8 g, 93%) was used in the next step without further purification 1H NMR (400 MHz, CDCl3) δ (ppm): 9.83 (s, 1H), 7.60 (d, 1H), 7.30 (m, 2H), 7.23 (m, 1H), 7.19 (m, 2H), 6.86 (dt, 1H), 3.21 (t, 2H), 3.03 (t, 2H).
