4-Piperidinoaniline

4-Fluoronitrobenzene (323 mg, 2.3 mmol) was dissolved in DMSO (5 ml), potassium carbonate (475 mg, 3.5 mmol) and piperidine (460 μl, 4.6 mmol) were added, and the mixture was stirred at 90° C. for 9 hr. A suspension of 1.01 g (5 mmol) 1-bromo-4-nitrobenzene, 1.5 g KSynthesis of 4-Piperidin-1-yl-phenylamine The second step: to install a magnetic stir, thermometer, condenser 500mL three-necked flask is addedThe first step in the reaction of 15.0g of 4-nitrophenyl piperidine powder, 2.0g of 10percent mass fraction of Pd / C, 180mL of ethanol was added as a solvent, and stirred to obtain a uniform suspension. After heating to reflux, the suspensionWas slowly added dropwise 45.0g of mass fraction of 80percent hydrazine hydrate solution, stirring continued at reflux for 12h. The reaction was completeCompleted, the reaction solution was filtered hot to remove Pd / C, the filtrate was concentrated under reduced pressure to 1/4 of its original volume, under a nitrogen atmosphereCooling and crystallization, to obtain a gray 4-aminophenyl-piperidine 10.2 g of crystals, 80percent yield;In a 500mL round-bottom flask, 28.3g (0.14mol) of nitro compound 1, 0.2g of 10 wtpercent Pd/C, 20mL hydrazine monohydrate and 180mL of ethanol was stirred at a reflux temperature for 10h. The solution was filtered hot to remove Pd/C, and the filtrate was evaporated under reduced pressure to dryness. A deep purplish red liquid was obtained. The product (2) was used for the next step without further purification. The yield was 18.1g (75percent). IR (KBr): 3429, 3346cmGeneral procedure: The compound S1 (261 mg, 1.25 mmol), iron powder (210 mg, 4.76 mmol, 3 equiv.) and ammonium chloride (335 mg, 6.27 mmol, 5 equiv.) were dissolved in methanol : water (2 : 1, 15 mL). The reaction mixture was heated at 100 °C overnight, cooled to RT, filtered through celite and the solvent was reduced under vacuum. The condensed mixture was extracted with DCM, washed with brine, dried with sodium sulfate and all solvent was evaporated to furnish the condensed residue, which was purified by flash chromatography (elution system - EA/Hexane = 1 : 1 ) to obtain the title compound (245 mg, 1.43 mmol).General procedure: An oven-dried Schlenk tube was charged with the aryl halide (2 mmol) and amine (2.5 mmol), FeOA–Pd (0.05 g, 0.04 mmol, 1.5 molpercent), base (3 mmol), solvent (5 mL) and additive. The resulting mixture was stirred for the appropriate time and temperature. After reaction completion the reaction mixture was then cooled to room temperature and the catalyst separated using a magnet, taken up in EtGeneral procedure: An oven-dried Schlenk tube was charged with the aryl halide (2 mmol) and amine (2.5 mmol), FeOA–Pd (0.05 g, 0.04 mmol, 1.5 molpercent), base (3 mmol), solvent (5 mL) and additive.
