Participants

Reaction Steps

To a solution of 1-oxo-2,3,4,5-tetrahydro-1H-[1,4]diazepino[1,2-a]indole-8-carboxylic acid (Intermediate J, 2.3 g, 9.2 mmol) in DMF (30 mL) are added N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (3.7 g, 9.7 mmol) and N-methylmorpholine (2.5 mL, 22.5 mmol). The reaction mixture is stirred for 1 h at room temperature and 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (2.4 g, 11.1 mmol) is added. The reaction mixture is stirred for 16 h at room temperature and is poured into water (200 mL). The resulting solid is collected by filtration, rinsed with water and dried to afford the title compound (3.8 g, 92%).
