Chlorophenyl isocyanate → HCID 178518972, compound

Participants

Reaction Steps

2-Chlorophenylisocyanate (7 g) and trimethylsilyl azide (7.9 g) were mixed and heated under refluxing for eight hours. The excessive trimethylsilyl azide was distilled off under reduced pressure and to the residue there were added 40 ml of methanol. Thereafter, the methanol was evaporated and the residue was purified by flush column chlomatography (hexane:ethyl acetate=2:1) to obtain the desired 1-(2-chlorophenyl)-5(4H)-tetrazolinone (7 g) having a melting point in the range of from 124.5° to 125.5° C.
