Methyl 5-(4-chlorophenyl)-3-{[(1E)-(dimethylamino)methylene]amino}thiophene-2-carboxylate (0.131 g, 0.41 mmol) and (3R)-1-[3-(aminomethyl)phenyl]pyrrolidin-3-ol (0.062 g, 0.26 mmol, purity 80%) in phenol (0.5 g) were subjected to microwave heating at 150° C. for 1 h. The product was precipitated with ether and decanted. The solid residue was washed with MeOH and CH2Cl2 to give 0.66 g (57%) of the title compound. 1H NMR (400 MHz, DMSO-d6) δ 8.62 (s, 1H), 7.90 (s, 1H), 7.88 (d, 2H, J=8.7 Hz), 7.56 (d, 2H, J=8.7 Hz), 7.11 (t, 1H, J=7.9 Hz), 6.56-6.52 (m, 2H), 6.43 (d, 1H, J=7.5 Hz), 5.15 (s, 2H), 4.92 (d, 1H, J=7.5 Hz), 3.40-3.18 (m, 3H), 3.03 (bd, 1H, J=9-7 Hz), 2.07-1.95 (m, 1H), 1.91-1.82 (m, 1H). 13C NMR (100 MHz, DMSO-d6) δ 157.6, 156.1, 149.8, 149.6, 147.8, 137.4, 134.3, 131.3, 129.4, 127.9, 121.8, 121.7, 114.1, 110.9, 110.7, 69.2, 55.9, 48.9, 45.4, 33.6.
