Reaction Steps

A solution of the above synthesized 4-methoxycarbonyl-3-nitrophenyl isothiocyanate (149 mg, 0.62 mmol) in tetrahydrofuran (2.2 ml) was added dropwise to a solution of hydrazine monohydrate (94 mg, 1.87 mmol) in tetrahydrofuran (4.0 ml) at 0° C. over 20 minutes. After stirring at 0° C. for further 40 minutes, water was added, and the precipitated solid was filtered to obtain 142 mg of the desired product as a colorless solid (yield 85%).
