1-(3,4-diaminophenyl)propan-1-one

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of aniline (1.86 g, 20 mmol) in 50 mL of toluene was added SOCl2 (2.6 g, 22 mmol) dropwise at 0° C. and the mixture was then refluxed for 2 h. After cooling to rt, 1-(3,4-diaminophenyl)propan-1-one (1.65 g, 10 mmol) was added. The mixture was refluxed for 2 h, cooled, concentrated, and purified by flash chromatography to give the desired product (960 mg, 50%) as a yellow solid. 1H NMR (400 MHz, CDCl3) δ 8.62 (s, 1H), 8.21 (d, J=9.2 Hz, 1H), 8.06 (d, J=9.2 Hz, 1H), 3.15 (q, J=7.2 Hz, 2H), 1.30 (t, J=7.2 Hz, 3H). the mixture was then refluxed for 2 h The mixture was refluxed for 2 h cooled concentrated purified by flash chromatography

実験手順: To a solution of 1-(4-amino-3-nitrophenyl)propan-1-one (1.94 g, 10 mmol) in 50 mL of methanol was added 0.5 g 10% Pd/C and the mixture was hydrogenated under H2 (1 atm) at rt for 1 h. The mixture was filtered and the filtrated was concentrated to give the desired product (1.48 g, 90%). The mixture was filtered the filtrated was concentrated
