Procedure
To 3,5-dimethylphenol (12 g) were added lithium hydroxide monohydrate (4.2 g) and 4-methoxybenzyl chloride (14 mL) at 85° C., and the mixture was stirred for 1.5 hours. The reaction mixture was cooled to room temperature and purified by column chromatography on silica gel (eluent: dichloromethene) to give 2-(4-methoxybenzyl)-3,5-dimethylphenol (5.1 g).
Workup
- custompurified by column chromatography on silica gel (eluent: dichloromethene)
