Reaction Steps

Azetidin-3-yl-{2-[2-(2,4-difluoro-phenyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1-thia-10-aza-benzo[e]azulen-9-yl}-amine (452 mg, 1.0 mmol), Methanesulfonyl chloride (136 mg, 1.2 mmol), DIPEA (260 mg, 2.0 mmol) was dissolved in THF (10 mL). The reaction mixture was stirred at room temperature (r.t.) for 1 hour. LC-MS indicated the reaction was completed. To the reaction mixture was added 20 mL of water, the mixture was extracted with dichloromethane. The organic layer was dried over anhydrous sodium sulfate, and concentrated to dryness. The crude was purified by pre-HPLC to afford 363 (57.2 mg, yield: 11%). 1HNMR (DMSO-d6, 400 MHz): δ 9.50 (s, 1H), 8.72 (s, 1H), 8.31 (s, 1H), 7.97-7.91 (m, 2H), 7.77-7.72 (m, 2H), 7.48-7.43 (m, 2H), 7.15 (s, 1H), 6.99 (s, 1H), 6.72 (d, J=4.4 Hz, 1H), 4.31 (s, 2H), 3.86 (s, 2H), 3.33 (s, 2H), 3.15 (s, 2H), 2.75 (s, 6H).
