실험 절차

A solution of 2-fluoro-1-methoxy-4-(2-nitro-vinyl)benzene (1.5 g, Intermediate (2)] in THF (50 mL) is treated dropwise with a solution of lithium aluminum hydride in ether (23 mL, 1M). The mixture is heated at 40° C. for 3 hours, cooled to room temperature, diluted with ether and quenched with Na2SO4.10H2O (104 g). After standing at room temperature overnight the reaction mixture is filtered and the filtrate is evaporated. The residue is subjected to chromatography on silica gel eluting with EtOAc to give 2-(3-fluoro-4-methoxy-phenyl)-ethylamine [0.81 g, Intermediate (3)] as an oil. MS: 170 (M+H); 1H NMR (CDCl3): 6.9-7 (3H, m); 3.85 (3H, s); 2.95 (2H, t); 2.7 (2H, t).
