Reaction Steps

To a solution of 3-morpholin-4-ylmethyl-1H-indol-6-ol sodium salt (130 mg, 0.51 mmol) and 2-chloro-thiazolo[4,5-b]pyrazine (70 mg, 0.41 mmol) in DMF (1.4 mL) was added Cs2CO3 (43 mg, 0.12 mmol) and the resulting suspension was stirred (rt, 16 h). The reaction mixture was filtered and the solid was rinsed with EtOAc. The reaction mixture was concentrated in vacuo. The resulting residue was purified via reverse phase HPLC to provide the title compound as a white powder (38.3 mg, 26%). MS (ESI): mass calculated for C18H17N5O2S, 367.1; m/z found, 368.1 [M+H]+. 1H NMR (600 MHz, CDCl3): 8.51 (d, J=2.6, 1H), 8.32 (d, J=2.6, 1H), 8.21 (s, 1H), 7.83 (d, J=8.6, 1H), 7.45 (d, J=2.2, 1H), 7.21 (d, J=2.3, 1H), 7.12 (dd, J=8.6, 2.2, 1H), 3.75-3.69 (m, 6H), 2.51 (s, 4H).
