実験手順

Methyl 3-amino-5-(4-chlorophenyl)thiophene-2-carboxylate (0.639 g, 0.2390 mmol) was taken up in DMF-DMA (3 mL) and heated to 110° C. The reaction was stirred for 3 h and then concentrated. 3-Methoxy-4-(2-methyl-2-pyrrolidin-1-ylpropoxy)aniline (0.0631 g, 0.2390 mmol) in absolute ethanol (3 mL) was added to the residue and the mixture was then concentrated. Fresh absolute ethanol (1 mL) was added and the reaction heated to reflux. The reaction was stirred for 18 h and then cooled to RT and the precipitate was collected to give 0.010 g (0.020 mmol, 8%) of the product as a white solid. 1H NMR (CDCl3) δ 8.15 (s, 1H), 7.65 (d, 2H, J=8.3 Hz), 7.53 (s, 1H), 7.44 (d, 2H, J=8.5 Hz), 7.18 (d, 1H, J=8.3 Hz), 6.96 (s, 1H), 6.88 (d, 1H, J=8.3 Hz), 3.83 (s, 3H, 2.77 (s, 2H), 2.72 (bs, 4H), 1.78 (bs, 4H), 1.36 (s, 6H).
