実験手順

To a solution of 2-[2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a,9-triaza-benzo[e]azulen-8-yloxy]-3-methyl-butyric acid methyl ester (160 mg, 0.38 mmol) in methanol (5 mL) and water (1 mL) was added lithium hydroxide monohydrate (18 mg, 0.45 mmol) and the reaction mixture stirred at 50° C. for 2 h. The reaction mixture was concentrated in vacuo and the resultant residue azeotroped with acetonitrile (3×20 mL). The residue was dissolved in DMF (3 mL), HATU (286 mg, 0.75 mmol), ammonium chloride (60 mg, 1.12 mmol) and triethylamine (157 μL, 1.12 mmol) added and the reaction mixture stirred at RT for 1 h. The reaction mixture was diluted with ethyl acetate, washed with water, extracting with ethyl acetate (3×15 mL). The combined organic extracts were washed with brine, dried (MgSO4) and concentrated in vacuo. The residue was subjected to reverse phase preparative HPLC (C-18, 10-90% MeCN in water 0.1% formic acid, 25 min gradient) to yield 452 as a white solid (28 mg, 43%). LCMS: RT=3.61 min, [M+H]+=412; 1H NMR (400 MHz, d6-DMSO) 9.04 (1H, s), 7.87 (1H s), 7.86 (1H, s), 7.31 (1H, br s), 7.08 (1H, br s), 6.43 (1H, s), 5.86 (1H, sept, J=6.56 Hz), 4.97 (1H, d, J=4.91 Hz), 4.61-4.43 (4H, m), 2.21-2.08 (1H, m), 1.43 (6H, dd, J=6.6, 3.6 Hz), 0.94 (6H, dd, J=6.6 Hz, 1.5 Hz)
