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 Et3N (0.21 mL, 1.51 mmol) and the reaction mixture was stirred (rt, 15 min). The resulting solution was treated with trimethylsilyl isocyanate (0.14 mL, 0.91 mmol) and stirred (rt, 4 h). The reaction mixture was concentrated in vacuo and the resulting residue was purified by reverse phase HPLC to afford the title compound as a white solid (55 mg, 44%). MS (ESI): mass calcd. for C20H19N5O3S, 409.47; m/z found, 410.0 [M+H]+. 1H NMR (400 MHz, CDCl3): 8.56 (dd, J=4.8, 1.6, 1H), 8.02 (dd, J=7.9, 1.6, 1H), 7.77 (d, J=8.5, 1H), 7.59 (d, J=1.9, 2H), 7.29 (dd, J=8.5, 2.1, 1H), 7.21 (dd, J=7.9, 4.8, 1H), 4.43 (s, 2H), 3.66 (d, J=0.7, 2H), 3.47-3.36 (m, 4H), 2.55-2.46 (m, 4H).
