Participants

Reaction Steps

To a stirred slurry of 2-{trans-4-[4-(4-amino-5-oxo-7,8-dihydropyrimido[5,4-f][1,4]oxazepin-6(5H)-yl)phenyl]cyclohexyl}acetamide (45 mg, 0.11 mmol), from Example 30, in THF (1 mL) was added DMF (0.002 mL) and oxalyl chloride (0.05 mL, 0.6 mmol). After two hours of stirring at room temperature, the reaction was quenched with aqueous sodium bicarbonate and extracted with EtOAc. The organic layer was washed with water, dried over sodium sulfate and concentrated in vacuo to afford the title compound as a light-yellow colored solid, 34 mg. 1H NMR (400 MHz, DMSO-d6): δ 8.17 (s, 1H), 7.63 (br s, 2H) 7.22 (m, 4H), 4.57 (m, 2H), 3.90 (m, 2H), 2.43 (m, 3H), 1.78 (m, 4H), 1.63 (m, 1H), 1.43 (m, 2H), 1.08 (m, 2H). m/z=378.3 (M+1). IC50 64.3 nM (range 51.2-91.1 nM).
