Participants

Reaction Steps

To a brown clear solution of 3-chloroquinoline-4-carbaldehyde (A275-3) (0.362 g, 1.89 mmol) in THF (1.9 mL) at room temperature was added potassium carbonate (0.078 g, 0.566 mmol) and nitromethane (1.420 mL, 26.4 mmol). The brown homogeneous mixture was stirred at room temperature. After 4 h, the reaction mixture was quenched with water (50 mL) and extracted with EtOAc (2×50 mL). The organic extract washed with saturated NaCl (1×50 mL), and dried over Na2SO4. The solution was filtered, concentrated in vacuo, and dried under high vacuum to give 1-(3-chloroquinolin-4-yl)-2-nitroethanol (A275-4) as a brown solid. 1H NMR (400 MHz, DMSO-d6) δ 8.88-8.93 (1H, m), 8.73 (1H, dd, J=8.6, 0.8 Hz), 8.08 (1H, dd, J=8.4, 1.0 Hz), 7.82 (1H, ddd, J=8.4, 6.9, 1.5 Hz), 7.72 (1H, ddd, J=8.5, 6.9, 1.4 Hz), 6.91 (1H, dd, J=4.5, 1.0 Hz), 6.26 (1H, ddd, J=10.0, 4.6, 3.6 Hz), 5.03-5.12 (1H, m), 4.94-5.01 (1H, m); LC-MS (ESI) m/z 253.1 (M+H)+.
