Sodium Chlorite → 3-chloro-4-(2-methylpropyl)Benzoic acid

참여 물질

반응 단계

A mixture of sodium chlorite (80% assay, 1.06 g, 0.0094 mol) and sodium dihydrogenphosphate dihydrate (3.33 g, 0.0213 mol) in demineralized water (10 mL) is added in two equal lots (one hr interval) to a solution of 3-chloro-4-isobutylbenzaldehyde (0.7 g, 0.0036 mol) in tert-butanol (10 mL) at room temperature. After completion of addition, stirring at room temperature is continued for 4 hrs. It is then extracted in ethyl acetate (2×30 mL). Combined organic layer is dried over sodium sulfate and concentrated under reduced pressure to give 3-chloro-4-isobutylbenzoic acid.
