Reaction Steps

To a mixture of [2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diazabenzo[e]azulen-9-yl]acetic acid trifluoroacetic acid salt from Example 120 (100 mg, 0.21 mmol), HATU (96 mg, 0.25 mmol) and NEt3 (63 mg, 0.63 mmol) in DMF (2 mL) was added a solution of phenylamine (23 mg, 0.25 mmol) in DMF (0.2 mL) and the resulting mixture stirred at RT for 16 h. The reaction mixture was loaded onto an Isolute® SCX-2 cartridge which was washed with MeOH and the product eluted with 2M NH3/MeOH. The resulting residue was purified by column chromatography (Si-PCC, gradient 0-8% MeOH in DCM) affording 119 as a white solid (51 mg, 57%). LCMS: RT 4.09 min [M+H]+ 429.3. 1H NMR (CDCl3, 400 MHz): δ 8.43 (1H, d, J=2.27 Hz), 7.91 (1H, s), 7.72 (1H, s), 7.47 (2H, d, J=8.02 Hz), 7.43 (1H, s), 7.29-7.26 (2H, m), 7.09-7.06 (2H, m), 5.86-5.85 (1H, m), 4.46-4.45 (4H, m), 3.78 (2H, s), 1.55 (6H, d, J=6.61 Hz)
