Procedure

To a suspension of 2-(3-piperazin-1-ylmethyl-benzofuran-6-yloxy)-thiazolo[4,5-b]pyridine hydrochloride (122 mg, 0.30 mmol) in DCM (3 mL) was added DIEA (158 μL, 0.91 mmol) and the reaction mixture was stirred (rt, 15 min). The resulting solution was treated with MsCl (26 μL, 0.33 mmol) and the resulting solution was stirred (rt, 2 h). The reaction mixture was partitioned with EtOAc and brine (20 mL each) and the organic layer was dried, filtered and concentrated in vacuo. The resulting residue was purified by reverse phase HPLC to provide the title compound as a white solid (42 mg, 31%). MS (ESI): mass calcd. for C20H20N4O4S2, 444.54; m/z found, 445.0 [M+H]+. 1H NMR (400 MHz, CDCl3): 8.56 (dd, J=4.8, 1.6, 1H), 8.03 (dd, J=7.9, 1.7, 1H), 7.74 (d, J=8.5, 1H), 7.62-7.56 (m, 2H), 7.30 (dd, J=8.5, 2.1, 1H), 7.21 (dd, J=8.0, 4.8, 1H), 3.69 (d, J=0.5, 2H), 3.32-3.21 (m, 4H), 2.79 (s, 3H), 2.67-2.54 (m, 4H).
