Participants

Reaction Steps

A solution of 4.95 g (18 mmol) 5-bromo-3-methoxy-N*2*-(2-methoxy-ethyl)-benzene-1,2-diamine, 5.15 g (27 mmol) EDC, 3.3 g (27 mmol) 4-dimethylamino-pyridine and 2.94 g (18 mmol) 4-isopropyl benzoic acid in 150 ml dichloromethane is stirred at room temperature for 14 h. After that 400 ml EtOAc are added and the organic phase washed with water (2×) and brine, dried over MgSO4, filtered and concentrated in vacuo. The residue is purified by flash-chromatography on silica gel (hexane:EtOAc=3:1) to afford 7.48 g of the title compound as a reddish oil.
