Procedure

1-Methyl-7-(4-(trifluoromethoxy)phenyl)-3,4-dihydro-1H-benzo[e][1,4]diazepine-2,5-dione (22.9 mg, 0.065 mmol) and NaH (15.6 mg, 0.650 mmol, 10.0 equiv.) were placed in a 0.5-2 mL Smith process vial. To the vial was added DMF (0.5 mL) followed by 2-(chloromethyl)pyrimidine hydrochloride (53.9 mg, 0.327 mmol, 5 equiv.) was added at room temperature. After stirring for 50 min, reaction was quenched with AcOH. Resulting mixture was filtered and purified via preparative reverse phase HPLC to give the title compound (2.2 mg) as a clear yellow film.
