Reaction Steps

A mixture of 6-(6-chloro-5-(dimethylamino)pyridin-3-yl)benzo[d]thiazol-2-amine (70 mg, 230 μmol), HATU (210 mg, 552 μmol), and 2-(dimethylamino)acetic acid (45 mg, 436 μmol) in DMF (2.5 mL) was heated to 60° C. for 2 h. The solution was diluted with H2O (20 mL) until it became cloudy and cooled to rt. The mixture was filtered, washed with H2O (10 mL), Na2HCO3 (saturated, 5 mL), and H2O (5 mL). The filter was dissolved in MeOH (10%) in DCM and dried over MgSO4. The organic was filtered, concentrated to a yellow solid. This was further purified on silica using MeOH in EtOAc (0-5%) to give a light yellow solid. A second purification with 1:1 hexane-acetone removed the less polar impurity (NAc) effectively, affording a white solid (30 mg). MS (ESI, POS. ION) M/Z: calc'd for C18H20ClN5OS: 389.1. found: 390.1. 1H NMR (400 MHz, chloroform-d) δ ppm 2.43 (s, 3H) 2.93 (s, 3H) 3.25 (s, 2H) 7.52 (d, J=2.15 Hz, 1H) 7.63 (dd, J=8.41, 1.76 Hz, 1H) 7.87 (d, J=8.41 Hz, 1H) 7.99 (d, J=1.56 Hz, 1H) 8.27 (d, J=2.15 Hz, 1H).
