Versuchsvorschrift

To a suspension of 8-azetidin-3-yl-2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene TFA salt 235 (200 mg, 0.42 mmol) in THF (3 mL) was added potassium carbonate (174 mg, 1.26 mmol) and 2-bromoacetamide (63 mg, 0.46 mmol) and the reaction mixture was stirred at RT for 18 hours. The volatiles were evaporated in vacuo and the residue partitioned between DCM and an aqueous saturated sodium bicarbonate solution. The organic layer was washed with water followed by brine, dried (MgSO4), concentrated in vacuo and the residue purified by flash chromatography (SiO2, 0-5% MeOH in DCM) to give 319 isolated as a cream solid after freeze drying from methanol and water (40 mg, 22%). LCMS: RT=3.03 min, [M+H]+=425. 1H NMR δ (ppm) (DMSO-d6): 8.26 (1H, d, J=8.18 Hz), 8.05 (1H, s), 7.20 (1H, dd, J=8.24, 1.83 Hz), 7.08 (1H, s), 7.00 (2H, d, J=1.87 Hz), 5.83-5.73 (1H, m), 4.34-4.28 (2H, m), 3.69-3.62 (2H, m), 3.63-3.52 (1H, m), 3.41-3.35 (2H, m), 3.21-3.14 (2H, m), 2.99 (2H, s), 1.50 (6H, d, J=6.59 Hz)
