Procedure

To a round bottom flask containing (4-{2-[2-(2,2,2-Trifluoro-ethyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-8-yl}-pyrazol-1-yl)-acetic acid (0.150 g, 0.000315 mol) in tetrahydrofuran (2.0 mL, 0.025 mol) was added N,N-diisopropylethylamine (0.33 mL, 0.0019 mol), ammonium chloride (0.10 g, 0.0019 mol) and N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (HATU) (0.24 g, 0.00063 mol). The reaction was stirred at room temperature overnight. The mixture was partitioned between saturated sodium bicarbonate and ethyl acetate. The organic phases were combined, dried with MgSO4, and concentrated. The crude was purified by reverse-phase HPLC to yield 240 (31.5 mg) as a colorless solid. MS (ESI+) 476.1.
