(2-Chlorophenyl)-(3,5-dichloropyrazin-2-yl)methanol → (2-Chlorophenyl)-(3,5-dichloropyrazin-2-yl)methanone

Participants

Reaction Steps

To a dichloromethane solution of (2-chlorophenyl)-(3,5-dichloropyrazin-2-yl)methanol (7.1 g, 24.5 mmol) was added portion wise solid manganese (IV) oxide (25 g, 245 mmol) and the resulting mixture was stirred at room temperature overnight. The reaction mixture was filtered and the filtrate was concentrated to give (2-chlorophenyl)-(3,5-dichloropyrazin-2-yl)methanone (6.02 g, 21 mmol, 85% yield). Mass spec., M+1=288.
