Uses
It is an intermediate of thiazoles.
Definition
ChEBI: N-(4-pyridyl)thiourea is a dihydropyridine.
Synthesis
P-pyridylthiourea was prepared as follows: 1,1-thiocarbonyldiimidazole (29.4 g, 0.16 mol) was added to an anhydrous tetrahydrofuran (600 mL) solution of 4-aminopyridine (14.1 g, 0.15 mol) and the resultant mixture was stirred for 17 hours. The solvent was removed under reduced pressure and the resulting solid was suspended in a mixture of dichloromethane and water. The undissolved solid was filtered and then washed with acetone to give a solid product (8.98 g). Gaseous ammonia was bubbled through a solution of anhydrous tetrahydrofuran (250 mL) of the resulting solid product (8.50 g, 0.06 mol) for 20 minutes. The ammonia flow was stopped and the mixture was stirred for 17 h, during which time a precipitate formed in the reaction. Filtering and then drying the solid under vacuum gave the desired thiourea product p-pyridylthiourea (5.1 g).
