Reaction Steps

5-(4-Chloro-phenyl)-3-(dimethylamino-methyleneamino)-thiophene-2-carboxylic acid methyl ester (0.100 g, 0.310 mmol), 4-(2-amino-ethyl)-N,N-diethyl-benzamide (0.082 g, 0.372 mmol) and phenol (1.0 g) were stirred at 135° C. for 2 hours. The reaction mixture was allowed to cool to r.t. and the product precipitated by the addition of MeOH (16 mL). The precipitate was filtered off and washed with MeOH to give the title compound. Yield: 0.058 g (40%). 1H NMR (400 MHz, CDCl3) δ 7.69 (s, 1H), 7.61 (d, 2H, J=8.67 Hz), 7.39-7.44 (m, 3H), 7.30 (d, 2H, J=8.19 Hz), 7.18 (d, 2H, J=8.19 Hz), 4.23 (t, 2H, J=7.05 Hz), 3.51 (bs, 1H), 3.46 (d, 2H, J=5.39 Hz), 3.21 (bs, 1H), 3.12 (t, 2H, J=6.64 Hz), 1.21 (bs, 3H), 1.08 (bs, 3H).
