Thiophosgene → 1-Cyclopropyl-4-isothiocyanatonaphthalene

Participants

Reaction Steps

Compound 2 (440 mg, 2.6 mmol) was dissolved in 14 mL of dichloromethane. Sodium bicarbonate (7 mL, sat solution) and thiophosgene (0.2 mL, 2.6 mmol) were added and the mixture stirred at room temperature for 1 h. Then, the organic layer was separated, dried over sodium sulfate and concentrated to afford 877 mg, 99% yield of 1-cyclopropyl-4-isothiocyanatonaphthalene (3) which was used in the next step without further purification
