Methanol → (4,5-Difluoro-2-nitrophenyl)methanol

Participants

Reaction Steps

To a solution of 3,4-difluoro-6-nitrobenzoic acid (3.05 g, 15 mmol) in THF (20 mL) was added BH3 THF (30 mL). The resulting mixture was stirred at room temperature for 2 h and then at 50° C. for 5 h. The resulting mixture was then cooled to room temperature, and methanol (20 mL) was added slowly. The resulting mixture was concentrated, and the residue was treated with methanol twice more, to yield a yellow solid.
