Participants

Reaction Steps

To a stirring mixture of (4-{2-[2-(2,4-difluoro-phenyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-2H-6-oxa-1,2-diaza-benzo[e]azulen-9-yl}-piperidin-4-yl)-methanol hydrochloride 75 (97 mg, 0.1873 mmol) in IMS (3 mL) was added DIPEA (165 L, 0.94 mmol) followed by vinyl sulfone (18 ul, 0.206 mmol) at RT, as illustrated in FIG. 16. After 3 h the solvent was removed in vacuo and the residue was subjected to HPLC (Gemini C6-Phenyl column, gradient 10 to 60%, 20 min ramp) to afford 188 (63 mg, 53%). 1H NMR δ ppm (DMSO-d6): 8.42-8.39 (1H, m), 8.23 (1H, s), 8.19 (1H, s), 7.80 (1H, td, J=8.77, 5.87 Hz), 7.53 (1H, ddd, J=10.34, 8.85, 2.77 Hz), 7.36 (1H, d, J=2.40 Hz), 7.33-7.27 (1H, m), 7.12 (1H, dd, J=8.59, 2.48 Hz), 6.85 (1H, dd, J=8.55, 4.83 Hz), 4.17 (2H, t, J=5.04 Hz), 3.22-3.14 (6H, m), 3.02 (2H, t, J=5.09 Hz), 2.98 (3H, s), 2.02 (2H, s), 1.72 (4H, s). 2 Protons obscured by water peak. LCMS: RT=6.57 min, M+H+=585
