Reaction Conditions

Reaction Steps

To a solution of 4-amino-3,5-dichlorobenzonitrile (2.00 g, 10.63 mmol) in acetonitrile (12 ml) was added dropwise tetrafluoroboric acid (2.80 ml, 21.27 mmol). After stirring for 10 min, isoamyl nitrite (1.50 ml, 10.63 mmol) was added and the reaction mixture was cooled to 0° C. After a further 10 min, diethyl ether (50 ml) was added and the resulting precipitate was collected by filtration and dried to give the titled compound (1.9 g).
