Reaction Steps

A mixture of (Z)-3-amino-N-(3-bromo-4-(dihexylamino)phenyl)but-2-enamide (5.10 g, 11.6 mmol) and triethyl orthoacetate (100 mL) was stirred at 150° C. overnight. The mixture was then cooled to rt and concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (V/V)=2:1) to give the title compound as pale yellow oil (1.74 g, 33%). The compound was characterized by the following spectroscopic data:
