실험 절차
8-Chloro-9-methoxy-4,6-dimethylbenzo[c][2,7]naphthyridin-5(6H)-one (0.04 g, 0.139 mmol) was subjected to Buchwald coupling (Example 16, Part H) with tert-butyl (1-hydroxy-2,4-dimethylpentan-2-yl)carbamate (0.048 g, 0.208 mmol) which afforded tert-butyl(1-((9-methoxy-4,6-dimethyl-5-oxo-5,6-dihydrobenzo[c][2,7]naphthyridin-8-yl)oxy)-2,4-dimethylpentan-2-yl)carbamate as white solid (15 mg, 0.029 mmol, 21% yield). LC/MS (ESI) m/e 484.2 [(M+H)+, calcd for C22H38N3O5, 484.3]; LC/MS retention time (Method C): tR=2.42 min.
