2-Amino-5-bromobenzenemethanol → 2-Amino-5-bromobenzaldehyde

Participants

Reaction Steps

A mixture of (2-amino-5-bromophenyl)methanol (10 g, 49.5 mmol) and MnO2 (25.8 g, 296.6 mmol) in CH2Cl2 (400 mL) was stirred at RT overnight. LCMS showed the reaction was completed. The solid was filtered off, and the filtrate was concentrated to give the title compound as a light yellow solid (8 g, 81%), which was directly used in next step without further purification. MS (ES+) C7H6BrNO requires: 199. Found: 200, 202 [M+H]+.
