Participants

Reaction Steps

To a solution of aniline 297 (200 mg, 0.455 mmol) in THF (20 mL) at 0° C. was added DIPEA (0.318 mL, 1.820 mmol) and triphosgene (81 mg, 0.273 mmol). The mixture was stirred at 0° C. for 1 hr before cyclopropylamine (0.160 mL, 2.275 mmol) was added, and was allowed to warm to RT over 1 hr. The mixture was concentrated and purified by Biotage (MeOH/DCM, 0-22%, SNAP 25 g cartridge) to afford title compound 298 (54 mg, 0.103 mmol, 22.7% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ (ppm): 8.69 (s, 1H), 8.50 (d, 1H, J=5.5 Hz), 7.89 (s, 1H), 7.70 (dd, 1H, J1=2.3 Hz, J2=13.9 Hz), 7.35 (t, 1H, J=9.0 Hz), 7.18-7.16 (m, 1H), 6.96 (s, 1H), 6.65 (d, 1H, J=5.5 Hz), 6.55-6.54 (m, 1H), 3.91 (s, 3H), 3.55 (t, 4H, J=3.4 Hz), 3.51 (s, 2H), 2.54-2.51 (m, 1H), 2.37 (m, 4H), 0.65-0.61 (m, 2H), 0.42-0.38 (m, 2H).
