To a suspension of 2-{4-[8-fluoro-2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diazabenzo[e]azulen-9-ylsulfanyl]piperidin-1-yl}-2-methylpropionic acid (174 mg, 0.329 mmol) in DMF (5 mL) were added DIPEA (169 l, 0.987 mmol), HOBt.NH3 (75 mg, 0.494 mmol) and EDCI (95 mg, 0.494 mmol) and the reaction mixture was stirred at RT for 18 h. The mixture was then partitioned between EtOAc and water and the aqueous phase was further extracted with EtOAc (×3). The combined organic layers were washed with water, followed by brine, then dried and concentrated in vacuo. The resulting residue was purified by column chromatography (Si-PCC, gradient 3-15% MeOH in DCM) affording the title compound as a colorless sticky solid (96 mg, 56%). LCMS: RT 2.16 min [M+H]+ 527.8
