2-Thiophenecarboxaldehyde (1.12 g, 10 mmol) was treated in the same manner as described above for the synthesis of 3-pentylamino-phthalic acid dimethyl ester. The residue (oil) was purified by preparative HPLC (Symmetry C18, isocratic, 45% acetonitrile/water) to give 0.88 g (58%) of yellow oil: 1H NMR (CDCl3) δ 7.38–7.15 (m, 3H), 7.00–6.93 (m, 2H), 6.87–6.82 (m, 2H), 4.58 (d, J=5.3 Hz, 2H), 3.86 (s, 3H), 3.83 (s, 3H).
