Procedure

A solution of crude {3-[2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-8-yl]-phenyl}-acetic acid (0.38 mmol) in 5 mL DMF was treated sequentially with DIPEA (0.33 mL, 1.92 mmol), ammonium chloride (164 mg, 3.1 mmol) and HATU (292 mg, 0.77 mmol). The reaction was monitored by LCMS. After complete conversion, the mixture was diluted with water and extracted with ethylacetate. The combined organics were washed with brine, dried over sodium sulfate and concentrated. The crude residue was purified by reverse phase HPLC to give 522 as a colorless solid (93 mg, 56%). LCMS: 446.1. 1H NMR (400 MHz, DMSO) δ 8.45 (d, J=8.3 Hz, 1H), 8.11 (s, 1H), 7.66 (s, 1H), 7.60 (d, J=7.8 Hz, 1H), 7.54 (dd, J=8.3, 1.8 Hz, 1H), 7.49 (s, 1H), 7.44-7.35 (m, 2H), 7.27 (d, J=7.6 Hz, 1H), 6.88 (s, 1H), 5.92-5.78 (m, 1H), 4.43 (t, J=4.9 Hz, 2H), 3.47 (overlapping m, 4H), 1.57 (d, J=6.6 Hz, 6H)
