Reaction Conditions:
with sodium tetrahydroborate in tetrahydrofuran at 0 - 20; for 4 h;Inert atmosphere;
Steps:
6; 68 Preparation of 3,5-dichloro-2-methoxybenzyl alcohol (Compound 6B)
Compound 6A (0.97 g, 4.78 mmol) was dissolved in 20 mL of dry THF.Sodium boron hydride (5.12 g, 19.2 mmol) was carefully added at 0 ° C under nitrogen.Stir at room temperature for 4 hours. After the reaction was completed, it was quenched with water and extracted with ethyl acetate three times.Drying to give compound 9B as a white solid.Directly used in the next reaction (0.99 g, 100% yield).
