1,2,3,5-tetrahydro-1,5-benzodiazepine-4-thione

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

Procedure: A mixture of 2,3,4,5-tetrahydro-1H-1,5-benzodiazepin-2-thione (0.8 g) and 0.80 g of N-formylhydrazine in 8 ml of n-butanol is stirred and refluxed for 18 hours and the solvent removed under vacuum. Ice water is added to the residual solid and the mixture filtered to give 0.312 g of a gray solid, m.p. 162°-165° C. refluxed for 18 hours the solvent removed under vacuum Ice water is added to the residual solid the mixture filtered

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