4-METHYL-2-NITROBENZYLALCOHOL Usage And Synthesis

Synthesis

General procedure for the synthesis of (2-amino-4-methylphenyl)methanol from (4-methyl-2-nitrophenyl)methanol: General method: (4-methyl-2-nitrophenyl)methanol (12) was dissolved in ethanol (concentration 0.2 M) and palladium/carbon catalyst (10% w/w, 5 mol%) was added. The reaction mixture was stirred for 1 h at room temperature under hydrogen atmosphere. The reaction process was monitored by thin layer chromatography (TLC). Upon completion of the reaction, the mixture was filtered through a diatomaceous earth pad and washed several times with ethyl acetate. The filtrate was concentrated under reduced pressure to obtain the crude product aniline, which was subsequently precipitated in a solvent mixture of petroleum ether and ethyl acetate (9:1, v/v). The precipitate was filtered and the solid was washed three times with a solvent mixture of the same ratio to give the final target product (2-amino-4-methylphenyl)methanol (11).
