Reaction Steps

To a mixture of 2-[2-(2,4-Difluoro-phenyl)-2H-[1,2,4]triazol-3-yl]-9-((3R,5S)-3,5-dimethyl-piperazin-1-yl)-4,5-dihydro-6-oxa-1-thia-10-aza-benzo[e]azulene (150 mg, 0.3 mmol), potassium carbonate (84 mg, 0.6 mmol) in DMF (5 mL) was added acetic anhydride (0.3 mL) at −15° C. The mixture was slowly warmed to room temperature and stirred for 30 min. The reaction mixture was added 30 mL of water. The solid was collected to give 100 mg of 312. Yield=62%. 1H NMR (CDCl3, 400 MHz): δ8.03 (s, 1H), 7.51-7.46 (m, 1H), 7.19-7.00 (m, 4H), 6.50 (d, J=8.8 Hz, 1H), 4.19 (t, J=4.4 Hz, 2H), 3.66-3.65 (m, 2H), 3.07 (t, J=4.8 Hz, 2H), 0.93-2.89 (m, 2H), 2.13 (s, 3H), 2.03 (s, 2H), 1.29-1.24 (m, 6H).
