Participants

Reaction Steps

A 0° C. solution of phosgene (20% in toluene, 0.711 mL, 0.980 mmol) in DCM (6 mL) was treated slowly drop-wise with a solution of Example B9 (0.129 g, 0.700 mmol) and pyridine (0.113 mL, 1.400 mmol) in DCM (2 mL), warmed to RT, stirred for 0.5 h, then concentrated to dryness. The residue was dissolved in DCM (2 mL), added to a 0° C. solution of Example A2 (0.058 g, 0.218 mmol) and TEA (0.091 mL, 0.654 mmol) in DCM (1 mL), warmed to RT and stirred for 0.5 h. The mixture was treated with water, stirred for 15 min and the layers separated. The organic layer was washed with additional water (2×), dried over MgSO4, concentrated to dryness and purified via silica gel chromatography (MeOH/DCM) to afford 3-(2-(1-methoxycyclopropyl)ethyl)-N-(5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)-2-oxoimidazolidine-1-carboxamide (25 mg, 24%) as a white solid. 1H NMR (400 MHz, DMSO-d6): δ 10.99 (s, 1 H), 8.37 (d, J=5.7 Hz, 1 H), 8.25 (s, 1 H), 8.22 (d, J=2.9 Hz, 1 H), 8.07 (d, J=9.0 Hz, 1 H), 7.96 (d, J=0.7 Hz, 1 H), 7.72 (dd, J=9.0, 2.9 Hz, 1 H), 7.22 (d, J=2.4 Hz, 1 H), 6.69 (dd, J=5.7, 2.4 Hz, 1 H), 3.84 (s, 3 H), 3.80 (m, 2 H), 3.50 (m, 2 H), 3.34 (m, 2 H), 3.17 (s, 3 H), 1.77 (t, J=7.4 Hz, 2 H), 0.67 (m, 2 H), 0.42 (m, 2 H); MS (ESI) m/z: 478.2 (M+H+).
