Reaction Steps

4-Benzyl-7-(4-(trifluoromethyl)phenyl)-3,4-dihydro-1H-benzo[e][1,4]diazepine-2,5-dione (9.80 mg, 0.024 mmol) and K2CO3 (10 mg, 0.072 mmol, 3.0 equiv.) were placed in a 0.5-2 mL Smith process vial under a nitrogen atmosphere. To the vial were added DMF (0.5 mL) and iodomethane (2.25 μL, 0.036 mmol, d=2.28 g/cm3, 1.5 equiv) at room temperature. After heating, stirred, at 60° C. for 2 hours, the reaction mixture was concentrated en vacuo. The resulting crude mixture was diluted with acetonitrile (1 mL), filtered through a syringe filter and injected into a preparative HPLC to give desired product (4-benzyl-1-methyl-7-(4-(trifluoromethyl)phenyl)-3,4-dihydro-1H-benzo[e][1,4]diazepine-2,5-dione, 1.8 mg) as a yellow film.
