反応手順

A mixture of (2-amino-5-bromo-3-fluorophenyl)methanol (13 g, 59.4 mmol) and manganese oxide (31 g, 356.4 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 (11 g, 85%) as a light yellow solid, which was directly used in the next step without further purification.
