Reaktionsschritte

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