Procedure

2-[2-(2,4-Difluoro-phenyl)-2H-[1,2,4]triazol-3-yl]-9-piperazin-1-yl-4,5-dihydro-6-oxa-1-thia-10-aza-benzo[e]azulene (150 mg, 0.3 mmol) was dissolved in THF, DIPEA (155 mg, 1.2 mmol) was added. Methanesulfonyl chloride (41 mg, 0.36 mmol) was added dropwise into the solution, and the reaction mixture was stirred at room temperature for 12 h. The reaction mixture was concentrated in vacuo, and then dissolved in DCM. The mixture was washed by water, dried over Na2SO4, concentrated in vacuo, and purified by prep. TLC (DCM/EtOAc=10:1) to give 130 (42.0 mg, yield: 26%). 1HNMR (Acetone, 400 MHz): δ8.00 (s, 1H), 7.73-7.71 (m, 1H), 7.36-7.10 (m, 2H), 7.12 (s, 2H), 6.69 (d, J=9.2 Hz, 1H), 4.14 (s, 1H), 3.49 (s, 4H), 3.22 (s, 4H), 3.00 (s, 2H), 2.79 (s, 3H). ESI-MS: m/z=545 [M+H+]
