Preparative Methods of 2-Amino-3-pyridinecarboxaldehyde: the reagent is best when freshly prepared. A multistep procedure starting from 2-amino-3- picoline has been improved upon by a simple two-step approach. Sulfamation of nicotinamide with ammonium sulfamate (both commercially available) provides 2-(3′-pyridyl)pyrido[2,3-d]pyridimine which may be hydrolyzed in 2 N HCl to provide the reagent (eq 1)[1]. Substituted derivatives of the reagent may be prepared via a similar intermediate.
