Reaction Conditions

Reaction Steps

2-Fluoro-5-nitro-benzaldehyde (11.9 g, 70 mmol) and 2-phenylethylamine (13 mL, 0.1 mol) were dissolved in methanol (150 mL) and glacial acetic acid (15 mL). The solution was cooled to 0° C., and sodium cyanoborohydride (6.6 g, 0.1 mol) was added portionwise. The reaction was adjusted to pH 6 with acetic acid and stirred at room temperature for 24 h. The reaction mixture was quenched with ice and diluted with water. The pH was adjusted to 11 with sodium hydroxide and the mixture was extracted with EtOAc. The organic extracts were washed with cold dilute HCl solution and a solid precipitated. Filtration yielded the title compound (15.6 g, 82%). Mp 235-6° C.; MS m/e 275 [M+H]+.
