Procedure

Anhydrous hydrazine (1.1 g, 0.035 mole) was dissolved in 150 ml of diethyl ether in a round-bottomed flask. 2-Naphthyl isothiocyanate (4.6 g, 0.25 mole) was added dropwise to the mixture keeping the pot temperature below 30° during the addition. The reaction mixture was stirred overnight at room temperature. The reactants were then cooled and the title product filtered off. The product was air-dried, yield 4.5 g, m.p. 174°-6°.
