Reaction Steps

A solution of 1.97 g (9.26 mmol) of 2-hydroxy-5-(1,1-dimethylethyl)-6-chlorobenzaldehyde and 1.98 g (11.1 mmol) of N-bromosuccinimide in 30 ml of methylene chloride was stirred for 2 hours. Water (50 ml) was added. The organic phase was dried and evaporated. The residue was chromatographed on 150 g of silica gel eluted with 1:99 (v/v) ether:hexane. There was obtained 2.69 g (9.22 mmol, 99%) of 2-hydroxy-3-bromo-5-(1,1-dimethylethyl)-6-chlorobenzaldehyde as a white solid after recrystallization from hexane; mp 103°-105° C.
