実験手順
A mixture of 3-fluoro-N,N-bis(3-methylbutyl)-4-nitrobenzamide (2.5 g, 1 eq, prepared according to Example A1), 3-diethylamino-propylamine (877 mg, 1.1 eq) and potassium carbonate (2.13 g, 2 eq) in acetonitrile (80 ml) is heated under reflux for 5 hours then concentrated under reduced pressure at 40° C. The residue is taken up in dichloromethane (130 ml) and water (50 ml). After decantation and extractions, the combined organic phases are washed with salt water, dried over Na2SO4 then concentrated under reduced pressure at 40° C. Purification of the residue by flash chromatography on silica gel (eluent: dichloromethane/methanol 9:1) produces the expected compound in the form of a yellow oil (2.1 g mg; 68% yield).
