3,4,5-Trimethoxybenzaldehyde 2.729 g and sodium borohydride 0.459 g were dissolved in methanol 20 ml, the reaction was stirred at room temperature for 30 min, adjusted to pH with dilute hydrochloric acid, and extracted with chloroform (10 ml 2).
8~9, extracted with chloroform (10 ml2), the organic phases were combined and washed with water (10 ml2), dried with anhydrous magnesium sulfate and filtered, the filtrate was evaporated to remove the solvent, to obtain oily 3,4,5-trimethoxybenzylalcohol 2.61 g, the yield was 95%.
