91.3% | With hydrogen bromide; In water; at 85 - 90℃; for 6h; | Preparation of 3-methylcatechol from 2-methoxy-6-methylcatechol:[00104] To a 250 ml of flask <strong>[2896-67-5]2-methoxy-6-methylphenol</strong> (5.0 g, 36.2 mmol) is charged along with 40 ml of a 48% aqueous hydrobromic acid solution. The mixture is heated to 85- 90 C for 6 hours. After cooling to room temperature, the mixture was extracted with ethyl acetate. The ethyl acetate extract is washed with water and brine, and then dried over magnesium sulfate. After filtration, the filtrate is concentrated, and dried in vacuo to yield 4.1 g (91.3%) of the product as a yellowish liquid. NMR: 6.71 (s, 3H), 5.20 (br.s, 2H), 2.25 (s, 3H). |
