2-Amino-5-methylphenol Use and Manufacturing

Methods of Manufacturing

To a solution of 5-methyl-2-nitrophenol (1.0 g, 6.53 mmol) in methanol (10 mL) at 23° C. was added Pd/C (10 wt percent, 400 mg), and the reaction mixture was deoxygenated under vacuum, then purged with hydrogen in a balloon. After stirring for 5 h, the reaction mixture was filtered through a pad of Celite and the Celite pad was rinsed with methanol (100 mL). The filtrate was concentrated in vacuo to yield 2-amino-5-methylphenol (801 mg, 100percent).

Uses

For organic synthesis
