Reaction Steps
Following Method 9, tert-butyl 5-(3-aminopyridin-4-yl)-2-oxohexahydrobenzo[d]oxazole-3(2H)-carboxylate and 6-bromo-5-fluoropicolinic acid were coupled and following addition of EtOAc and washing with H2O, NaCl(sat.) and drying over MgSO4, tert-butyl 5-(3-(6-bromo-5-fluoropicolinamido)pyridin-4-yl)-2-oxohexahydrobenzo[d]oxazole-3(2H)-carboxylate was obtained. LCMS (m/z): 537.1 (MH+); LCMS Rt=0.71 min.
