Versuchsvorschrift

To a solution of o-bromo-benzaldehyde (4 g, 21.6 mmol) and nitromethane (1.32 g, 21.6 mmol) in methanol (5 mL) was added NaOH (0.908 g, 22.7 nmol) in 1 mL of H2O. After 45 minutes, the precipitate was dissolved in 10 mL of H2O. The product precipitated out after the addition of 6N HCl. The product was recrystallized from ethanol; 0.312 g (6%).
