Reaction Steps

A mixture of tert-butyl 1-(4-(1-bromo-8-phenyl-4H-pyrido[2,3-b][1,2,4]triazolo[4,3-d][1,4]oxazin-7-yl)phenyl)cyclobutylcarbamate (41 mg, 0.071 mmol), dimethylamine hydrochloride (58.2 mg, 0.714 mmol), and triethylamine (0.099 ml, 0.714 mmol) in NMP (1 ml) was heating at 130 degree for 50 min under microwave condition. The mixture was diluted with DCM (8 ml) and water (8 ml). The organic phase was washed with water (8 mlX3) and brine (5 ml). Concentrated and purified by column eluted with MeOH/DCM (0-4%) to give product (8 mg). 1H NMR (500 MHz, CDCl3) 8.15 (s, 1H), 7.15-7.34 (m, 9H), 5.51 (s, 2H), 5.01 (s, 1H), 2.95 (s, 6H), 2.4-2.5 (m, 4H), 2.0-2.15 (m, 1H), 1.75-1.85 (m, 1H), 1.2-1.35 (m, 9H).
