Reaction Steps

A mixture of 2-(6-(4-chlorophenyl)-1-methyl-5-oxo-5,6-dihydro-4H-benzo[b][1,2,4]triazolo[4,3-d][1,4]diazepin-4-yl)acetic acid (15 mg, 0.04 mmol), ethanamine (4 mg, 1.12 mmol), HATU (19 mg, 0.05 mmol), DIEA (8 mg, 0.06 mmol) in DCM (5 mL) was stirred overnight at room temperature. The mixture was concentrated and purified by prep-HPLC to give 2-(6-(4-chlorophenyl)-1-methyl-5,6-dihydro-4H-benzo[b][1,2,4]triazolo[4,3-d][1,4]diazepin-4-yl)-N-ethylacetamide as a white solid (4 mg).
