Reaction Steps

To a solution of 7.7 g (0.24 mole) anhydrous hydrazine in 200 ml of dry ether, N-methyl-N-phenylthiocarbamyl chloride (20.4 g, 0.11 mole) was added below 5° C. with stirring. The mixture was stirred and allowed to warm to room temperature. The mixture was filtered and the residue resuspended in about 100 ml water and stirred.
