Procedure
A solution of hexamethylene di-isocyanate (1.68g.) in toluene (10ml.) was added to a solution of 3-aminopyridine (1.88g.) in toluene (18ml.) and the mixture was heated on a steam-bath for 10 minutes. The mixture was cooled, and the product was filtered off, washed with toluene and dried, to give 1,6-bis[3-(pyrid-3-yl)ureido]hexane, m.p. 197°-199°C., the starting material for compound 67.
