1. To a solution of 2,3-dichlorobenzaldehyde (500 g, 2.85 mol) in methanol (3.5 L) was slowly added an alkaline solution of sodium borohydride (113.5 g, 2.975 mol) dissolved in 0.2 N sodium hydroxide solution (241 mL) at 0°C. The addition process lasted for 1 hour. The reaction mixture was stirred at room temperature for 2 hours. Subsequently, the reaction mixture was quenched by slowly pouring it into water (3.7 L) and the pH was adjusted to 6 with glacial acetic acid (125 mL). the precipitated white solid was collected by filtration to afford 2,3-dichlorobenzyl alcohol (467 g, 92% yield).
