Reaction Steps

To a solution of 1-naphthalenylisothiocyanate (500 mg, 2.7 mmol) in ethanol (150 mL) was added sodium azide (2.8 g, 43 mmol) and the mixture was heated to 79° C. for 2 hours. The reaction mixture was then cooled to room temperature, aqueous HCl solution (12N, 1.5 mL) added and the mixture concentrated. The resulting residue was diluted with ethyl acetate and extracted with aqueous NaOH solution (1N) and the aqueous layer acidified with aqueous HCl solution (12N) until a precipitate formed. The precipitate was collected and used in the next step without further purification (520 mg, 85% yield).
