Reaction Steps

The title compound was synthesized following the procedure described for INTERMEDIATE 10, using 3-(trans-3-aminocyclobutyl)-1-methyl-1H-imidazo[4,5-b]pyridin-2(3H)-one dihydrochloride (0.146 g, 0.501 mmol), diisopropylethylamine (1 ml, 5.75 mmol), 4-dimethylaminopyridine (6.13 mg, 0.050 mmol), and 2-chlorobenzoxazole (0.057 ml, 0.501 mmol) in DMSO (0.5 mL) to afford 3-(trans-3-(benzo[d]oxazol-2-ylamino)cyclobutyl)-1-methyl-1H-imidazo[4,5-b]pyridin-2(3H)-one (0.102 g, 0.304 mmol, 60.7% yield). m/z: 336.2 (M+1); 1H NMR (400 MHz, DMSO-dh) δ: ppm 8.44 (d, J=5.87 Hz, 1 H), 8.04 (d, J=4.69 Hz, 1 H), 7.50 (d, J=7.43 Hz, 1 H), 7.37 (d, J=7.82 Hz, 1 H), 7.28 (d, J=7.63 Hz, 1 H), 7.05-7.19 (m, 2 H), 6.92-7.03 (m, 1 H), 5.26 (t, J=8.22 Hz, 1 H), 4.53 (br. s., 1 H), 3.23-3.46 (m, 5 H), 2.38-2.61 (m, 2 H).
