To a solution (R)-2-{2-[2-(2,2,2-trifluoro-ethyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-yloxy}-propionic acid ethyl ester in methanol (3 mL) was added water (1 mL) and lithium hydroxide monohydrate (11 mg, 0.42 mmol). The reaction mixture was stirred at RT for 16 h then HCl (1N, aq.) added until pH˜4. The reaction mixture was concentrated in vacuo. The resultant residue was dissolved in DMF (3 mL) and HATU (217 mg, 0.56 mmol), ammonium chloride (45 mg, 0.85 mmol) and triethylamine (119 μL, 0.85 mmol) added. The reaction mixture was stirred at RT for 1 h before being concentrated in vacuo. The residue was dissolved in ethyl acetate (10 mL) and the mixture washed with water, extracting with ethyl acetate (3×10 mL). The combined organic extracts were washed with brine, dried (MgSO4) and concentrated in vacuo. The resultant residue was subjected to flash chromatography (SiO2, gradient 0-10% methanol in ethyl acetate) to give 487 as a white solid (49 mg, 40%). LCMS: RT=3.52 min, [M+H]+=423; 1H NMR (400 MHz, d6-DMSO) 8.22 (1H, d, J=8.9 Hz), 8.03 (1H, s), 7.95 (1H, s), 7.51 (1H, br s), 7.22 (1H, br s), 6.73 (1H, dd, J=8.9, 2.6 Hz), 6.50 (1H, d, J=2.6 Hz), 5.86 (2H, q, J=8.9 Hz), 4.64 (1H, q, J=6.6 Hz), 4.51-4.38 (4H, m), 1.40 (3H, d, J=6.4 Hz)
