(2-Amino-5-bromo-3-chlorophenyl)methanol → 2-Amino-5-bromo-3-chlorobenzaldehyde

Participants

Reaction Steps

A mixture of (2-amino-5-bromo-3-chlorophenyl)methanol (10.0 g, 42.5 mmol) and manganese oxide (21.9 g, 255 mmol) in dichloromethane (400 mL) was stirred at room temperature overnight. The solid was filtered off, and the filtrate was concentrated to give the title compound as a light yellow solid (9.0 g, 91%), which was directly used in the next step without further purification.
