6-Bromo-2-hydroxynaphthalene

6-Methoxy-2-naphthaldehyde is prepared by Grignard reaction of 6-bromo-2-methoxylnaphthalene,which is synthesized from 2-naphthol via bromination first then reduction and methylation or methylation first then bromination and reduction.

以2-萘酚为起始原料,经过溴化、还原和甲基化或先经过甲基化,再溴化还原两条路线制得6-溴-2-甲氧基萘,再经格氏反应制得6-甲氧基-2-萘甲醛。
