실험 절차

To a solution of 2-(4-isopropyl-4H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene-8-carbaldehyde (180 mg, 0.53 mmol) in DCE (7 mL+5% AcOH) was added trifluoroethylamine (46 μL, 0.58 mmol) and the mixture was stirred for 30 minutes. Sodium triacetoxyborohydride (134 mg, 0.64 mmol) was added and the solution was stirred under nitrogen for 65 hours. The reaction mixture was diluted with aqueous saturated sodium bicarbonate solution and DCM and the phases were separated. The organic layer was washed with brine, dried (Na2SO4) and concentrated in vacuo. The resultant residue was purified by flash chromatography (SiO2, 0-5% 2M NH3/MeOH in DCM) to give a colourless oil. The oil was triturated with ether/cyclohexane to give 119 as a grey solid (138 mg, 61%). LCMS: RT=9.52 min, [M+H]+=424. 1H NMR δ (ppm) (DMSO-d6): 8.91 (1H, s), 8.22 (1H, d, J=8.10 Hz), 7.09 (1H, dd, J=8.16, 1.68 Hz), 7.00 (1H, d, J=1.64 Hz), 5.49-5.39 (1H, m), 4.33-4.27 (2H, m), 3.74 (2H, s), 3.40-3.32 (2H, m), 3.21-3.09 (2H, m), 2.92 (1H, s), 1.52 (6H, d, J=6.71 Hz)
