[(2-hydroxyphenyl)methylideneamino]thiourea

Conditions: temp:75.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Salicylaldehyde was added dropwise over 5 min. to a solution of thiosemicarbazide (5.47 g, 60 mmol) in 75 mL water maintained at 75° C. A white solid began to precipitate immediately. The resulting mixture was heated to reflux for 2 hours, then cooled to room temperature and filtered to give salicylaldehyde thiosemicarbazone (11.5 g, 98%) as a white crystalline solid. to precipitate immediately The resulting mixture was heated to reflux for 2 hours cooled to room temperature filtered
