Reaction Steps

To 6-(hydroxymethyl)-3-methylbenzo[d]oxazol-2(3H)-one (45.1 μmol) was added the solution of 3-(4-(methylamino)-2-(pyridin-3-yl)quinazolin-6-yl)phenol (30 μmol) in THF (400 μL). After PS-triphenylphosphine (60 μmol) was added, the solution of DBAD (di-tert-butyl azodicarboxylate, 66 mmol) in THF was dispensed to the vials. The mixture was heated at 50° C. for 8 h. After the solvent was removed, the residue was diluted with methanol and purified by Mass triggered PREP-HPLC Condition D. The target fraction was lyophilized to afford the titled compound whose structure was finally confirmed by LCMS using LCMS Method E.
