実験手順

A 50 mL round bottom flask was dried in an oven overnight and cooled to room temperature under Ar(g). The flask was charged with fluoronitrobenzene (0.187 mL, 1.77 mmol), 2-Pyrrolidin-1-yl-ethylamine (0.201 g, 2.30 mmol) and dioxane (9.0 mL). To the solution, diispropyl ethyl amine (0.463 mL, 2.66 mmol) was added dropwise and allowed to stir at 105° C. for 48 h. The mixture was extracted with EtOAc (3ט30 mL), and with brine (2ט30 mL). The combined organic layers were then dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The crude mixture was then purified over silica (10% MeOH/90% CHCl3) affording (4-Nitro-phenyl)-(2-pyrrolidin-1-yl-ethyl)-amine as a yellow solid (0.352 g, 1.50 mmol, 85% yield).
