Triethylamine → 1-(4-Aminophenyl)-2-methylpropan-1-one

참여 물질

반응 단계

p-Nitroisobutyrophenone from step 4 (1.0 g, 0.0058 mol), was dissolved in DMF (5 ml). SnCl2.2H2O (4.67 g, 0.0207 mol) is added and the reaction is stirred at room temperature. After 4 hours the reaction was poured into 100 ml of ethyl acetate. Excess Et3N (4 ml) was added and a white, solid precipitate formed. The suspension was filtered through celite. Evaporation of the filtrate left a yellow solid which was purified by column chromatography. The resulting crystalline solid (0.700 g, 4.2 mmol, 82%) had a 1H-NMR (DMSO): 7.71 (d, 2H), 6.58 (d, 2H), 6.03 (s, 2H), 3.45 (m, 1H), 1.06 (s, 6H)
