Versuchsvorschrift

Sodium nitrite (30 mL) was slowly added (over 2 hours) to 1-cyclopropyl-naphthalene (6.4 g, 38 mmol) stirred at 0° C. The reaction mixture was stirred at 0° C. for an extra 30 min and then was slowly poured into ice. Water was added, followed by EtOAc. After extraction, the organic layer was washed with a 1% aqueous solution of NaOH, then washed with water, dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography to yield 1-cyclopropyl-4-nitro-naphthalene (5.2 g, 64%).
