HCID 68409101Oxindole hydrazide

Procedure

An oxindole hydrazine derivative of formula (I) is admixed as a dry powder with a dry gelatin binder in an approximate 1:2 weight ratio. A minor amount of magnesium stearate is added as a lubricant. The mixture is formed into 240-270 mg tablets (80-90 mg of active oxindole hydrazide compound per tablet) in a tablet press.
