3-Fluoro-1-[2-(2-methoxy-4-nitrophenoxy)ethyl]pyrrolidine (0.0442 g, 0.1740 mmol) and methyl 5-(4-chlorophenyl)-3-{[(1E)-(dimethylamino)methylidene]amino}thiophene-2-carboxylate (0.056 g, 0.1740 mmol) were charged to a flask. Phenol (1 g) was added and the reaction heated to 200° C. The reaction was stirred for 45 min until all starting material was gone. The mix was then cooled to RT, diluted with CH2Cl2 (30 mL) and washed with 1N NaOH (2×30 mL), water (1×30 mL), brine (1×30 mL), dried over MgSO4, filtered, and concentrated. The residue was purified on a chromatatron (98:2 CH2Cl2:MeOH) to give 0.010 g (0.020 mmol, 11%) of the product as a tan solid. 1H NMR (CDCl3) δ 8.13 (s, 1H), 7.65 (d, 2H, J=8.3 Hz), 7.52 (s, 1H), 7.43 (d, 2H, J=8.4 Hz), 7.00 (d, 1H, J=8.4 Hz), 6.93 (m, 2H), 5.29-5.13 (m,1H), 4.23 (t, 2H, J=5.7 Hz), 3.88 (s, 3H), 3.12-2.93 (m, 5H), 2.68 (bs, 1H), 2.25-2.06 (m, 2H).
