Reaction Steps

In a 250 ml round-bottom flask equipped with a mechanical stirrer were mixed (benzyloxythiocarbonyl)hydrazine and 2N sodium hydroxide (90 ml). This mixture was stirred vigorously and cooled to 0° C. A solution of cyanogen bromide (14.5 g, 0.137 mol) in methanol (60 ml) was added dropwise at a rate that kept the reaction temperature between about 0°-5° C. A precipitate formed. When the addition was complete, the reaction mixture was filtered and the residue was rinsed well with water and dried in vacuo. The product was recrystallized from methanol/water to give a white solid of 16.6 g, 58.5% yield with a m.p. of 173°-175° C.
