Participants

Reaction Steps

To an ice-cooled solution of 7-iodo-8-phenyl-2H-9-oxa-1,2,3a-triaza-cyclopenta[a]naphthalene-3,6-dione in DMF (2 mL) was added cesium carbonate (73 mg, 0.224 mmol) and iodomethane (0.021 mL, 0.336 mmol). The mixture was allowed to warm to RT and stirred for 1.5 hours. The reaction mixture was partitioned between EtOAc and water. The aqueous phase was isolated and extracted twice with EtOAc. The combined organic extracts were washed with water and brine, dried (Na2SO4), filtered, and concentrated in vacuo to give the title compound (25.5 mg, 51%, over 2 steps) as a yellow solid. LCMS (Method A): RT=3.98 min, [M+H]+=420.
