Reaktionsschritte
39.0 g (0.2 mol) of methyl 2-methyl-3-nitrobenzoate was dissolved in 600 ml of tert-butanol, and 19.0 g of sodium borohydride was added thereto. Under refluxing, 150 ml of methanol was dropwise added thereto over a period of 1 hour. The refluxing was continued further for 1 hour to complete the reaction. The reaction mixture was left to cool, and then water was added thereto. The solvent was distilled off under reduced pressure. To the residue, water and chloroform were added, and the organic layer was separated and dried over anhydrous sodium sulfate. Then, the solvent was distilled off to obtain 30.7 g of 2-methyl-3-nitrobenzyl alcohol.
