A solution of 5-(4-methoxy-phenylsulfanyl)-thiazol-2-ylamine (70b, 3.0 g, 12.6 mmol), 3-pyridin-3-yl-propionic acid (2.30 g, 15.1 mmol), NEt3 (6.10 ml, 44.1 mmol), EDC (4.80 g, 25.2 mmol) and HOBt (3.40 g, 25.2 mmol) in DMF (150 mL) was stirred at room temperature for 18 hours. The reaction mixture was quenched with water and extracted with ethyl acetate. The organic layer was washed with brine, dried over MgSO4(s), and concentrated under reduced pressure to give N-[5-(4-methoxy-phenylsulfanyl)-thiazol-2-yl]-3-pyridin-3-yl-propionamide (70, 3.50 g) in 75% yield: 1H NMR (500 MHz, DMSO) δ 8.45 (d, 1H), 8.39 (m, 1H), 7.64 (m, 2H), 7.29 (m, 3H), 6.92 (t, 2H), 3.73 (t, 3H), 2.90 (t, 2H), 2.77 (t, 2H).
