2-Aminopyridine → HCID 13089302, compound

Participants

Reaction Steps

Into 45 ml of o-xylene, were added 1.5 g of ethyl N-(4-phenyl-2-thiazolyl)carbamate and 4.0 g of 2-aminopyridine. The mixture was stirred for 2.5 hours under refluxing. The reaction solution was allowed to stand for cooling. Deposited crystals were collected by filtration and washed with methyl alcohol. The crystals were then recrystallized from an N,N-dimethylformamide/methyl alcohol mixed solvent to obtain 1.2 g of N-(2-pyridyl)-N'-(4-phenylthiazol-2-yl)urea.
