Nitroethane → 1-(3-Bromophenyl)-3-nitrobutan-2-ol

Participants

Reaction Steps

To a solution of 2-(3-bromophenyl)acetaldehyde (5.0 g, 0.025 mol) and DBU (7.6 mL, 0.05 mol) in THF (300 mL), Nitroethane (1.0 g, 0.03 mol) was added at 0° C. over 10 min. The reaction mixture was stirred for 3 h, quenched by the addition of H2O (50 mL) and extracted with EtOAc (100 mL×3). The combined organic layers were washed with H2O (2×30 mL) and brine (1×20 mL), dried over Na2SO4, filtered and concentrated to afford 1-(3-bromophenyl)-3-nitrobutan-2-ol (3.0 g, 44%) as a yellow oil. MS (ES+) C10H12BrNO3 requires: 273, 275 found: 274, 276 [M+2+H]+(1:1).
