1,3-dihexylthiourea

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

Procedure: Prepared by the method described in Example 1 from N,N'-dihexylthiourea (114.2 g, 468 mmoles) and acetylenedicarboxylic acid (53.4 g, 468 mmoles). Recrystallization from acetonitrile gave the product (50.4 g) mp 66°-69° C. Prepared by the method Recrystallization from acetonitrile

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