Procedure

To a solution of 4-hydroxy-4-[2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-8-yl]-piperidine-1-carboxylic acid tert-butyl ester (20 mg, 39 μmol) in DCM (2 mL) was added TFA (0.5 mL) and the reaction mixture stirred at RT for 3 h. The reaction mixture was concentrated in vacuo and the resultant residue subjected to flash chromatography (Si—NH2, gradient 1-4% MeOH in DCM). The purified product was dissolved in MeOH (5 mL) and HCl (0.5 mL, 3N in MeOH) added. The reaction mixture was concentrated in vacuo and the residue triturated with MeCN to give 517 as a colourless solid (9 mg, 51%). LCMS: RT=2.94 min, [M+H]+=412 [ad823591] 1H NMR 400 MHz (d6-DMSO) δ: 8.38 (1H, d, J=8.2 Hz), 7.97 (1H, s), 7.28 (1H, dd, J=8.2, 1.9 Hz), 7.20 (1H, d, J=1.9 Hz), 5.93 (1H, sept, J=6.6 Hz), 4.37 (2H, t, J=5.0 Hz), 3.49-3.29 (6H, m), 2.29-2.17 (2H, m), 1.98-1.90 (2H, m), 1.59 (6H, d, J=6.6 Hz)
