Hydrochloric Acid → 1-(Chloromethyl)-2-fluoro-3-methoxybenzene

참여 물질

반응 단계

2-Fluoro-3-methoxybenzyl alcohol from Step 2 (12.16 g, 78 mmol) was dissolved in concentrated hydrochloric acid (60 mL) and hydrochloric acid gas was bubbled through the solution for 3 minutes. The reaction was stirred at room temperature (21 hours). The reaction mixture was extracted with ether, dried over MgSO4 and concentrated in vacuo to give 2-fluoro-3-methoxybenzyl chloride (10.36 g, 76%) as a green oil: 1H NNR (acetone-d6) 300 MHz 7.12 (m, 2H) 7.05 (m, 1H) 4.73 (s, 2H) 3.89 (s, 3H); 19F NMR (acetone-d6) 300 MHz -142.07(m).
