반응 단계

To a suspension of t-BuOK (20.15 g, 0.165 mol) in THF (250 mL) was added a solution of TosMIC (16.1 g, 82.6 mmol) in THF (100 mL) at −78° C. The mixture was stirred for 15 minutes, treated with a solution of 3-benzyloxy-4-methoxy-benzaldehyde (10.0 g, 51.9 mmol) in THF (50 mL) dropwise, and continued to stir for 1.5 hours at −78° C. To the cooled reaction mixture was added methanol (50 mL). The mixture was heated at reflux for 30 minutes. Solvent of the reaction mixture was removed to give a crude product, which was dissolved in water (300 mL). The aqueous phase was extracted with EtOAc (100 mL×3). The combined organic layers were dried and evaporated under reduced pressure to give crude product, which was purified by column chromatography (Petroleum Ether/EtOAc 10:1) to afford 2-(3-(Benzyloxy)-4-methoxyphenyl)acetonitril (5.0 g, 48%). 1H NMR (300 MHz, CDCl3) δ 7.48-7.33 (m, 5H), 6.89-6.86 (m, 3H), 5.17 (s, 2H), 3.90 (s, 3H), 3.66 (s, 2H). 13C NMR (75 MHz, CDCl3) δ 149.6, 148.6, 136.8, 128.8, 128.8, 128.2, 127.5, 127.5, 122.1, 120.9, 118.2, 113.8, 112.2, 71.2, 56.2, 23.3.
