실험 절차

A mixture of 5-methoxypentanal (0.644 g, 5.54 mmol), 3-(3-aminophenyl)-3-hydroxypropanenitrile (12) (1.0 g, 6.16 mmol) and activated molecular sieves in methanol was stirred at RT for 8 hrs. NaBH4 (0.937 g, 24.6 mmol) was added portion wise to the reaction mixture at 0° C. The reaction mixture was stirred at RT overnight. The reaction mixture was filtered through Celite and the filtrate was concentrated under reduced pressure. Purification by column chromatography (100-200 silica, 0% to 70% EtOAc—hexanes gradient) gave 3-hydroxy-3-(3-(5-methoxypentylamino)phenyl)propanenitrile as a yellow oil. Yield (0.34 g, 21%); 1H NMR (400 MHz, CDCl3) δ 7.17 (t, J=8.0 Hz, 1H), 6.66 (d, J=7.6 Hz, 1H), 6.62 (s, 1H), 6.56 (d, J=8.0 Hz, 1H), 4.95 (t, J=6.4 Hz, 1H), 3.39 (t, J=6.4 Hz, 2H), 3.33 (s, 3H), 3.12 (t, J=7.2 Hz, 2H), 2.75 (d, J=6.4 Hz, 2H), 1.68-1.59 (m, 4H), 1.51-1.43 (m, 2H).
