Participants

Reaction Steps

To 100 mL of THF at 0° C. was added dropwise over 20 min simultaneously a solution of 8.0 g of the N1-[2-oxo-2-(2,3,4,5-tetrahydro-1H-1-benzazepin-1-yl)ethyl]-N2-phenylbenzene-1,2-diamine (8.0 g, 21.5 mM) in 100 mL of THF and solution of malonyl dichloride (2.40 mL, 25.8 mM) in 100 mL of THF. The resulting solution was stirred at RT for 20 h and the solvent removed in vacuo. The resultant material was purified by silica gel flash column chromatography using hexanes/EtOAc 1/1 and the combined filtrates evaporated in vacuo to give 7.5 g of product.
