실험 절차

To a solution of 2-(diphenylmethyleneamino)-3-(4-fluorophenyl)propanenitrile (1.65 g, 5.02 mmol, 1.0 equiv) in THF (20.1 mL) was added HCl (5.53 mL of a 1 M aqueous solution, 5.53 mmol, 1.1 equiv). After stirring 3 h, the reaction was poured into water and washed with ether (×3). The aqueous layer was neutralized by the addition of 10 M NaOH and extracted with CH2Cl2 (×3). The combined CH2Cl2 extracts were dried (Na2SO4) and then concentrated in vacuo to provide the title compound (0.77 g, 93% yield) as a colorless oil. For convenience, the amine could be converted into the hydrochloride salt by dissolution in ether, treating with 2 M HCl in ether, and filtering the resulting white solid: 1H NMR (400 MHz, CDCl3) δ ppm 7.24-7.29 (m, 2H), 7.01-7.08 (m, 2H), 3.85-3.96 (m, 1H), 2.92-3.07 (m, 2H), 1.60 (d, J=7.55 Hz, 2H).
