Versuchsvorschrift

A suspension of 3-fluoro-5-methoxy-4-nitrobenzonitrile (940 mg, 4.8 mmol) in a mixture of concentrated H2SO4 and water (2 mL/2 mL) was heated at 100° C. overnight. The reaction mixture was then cooled down, solid filtered and dried to give the product as brown solid (770 mg, 75%).
