Participants

Reaction Steps

A mixture of 2-amino-5-iodobenzoic acid (2.0 g, 7.6 mmol) and formamidine acetate (0.99 g, 9.5 mmol) in absolute ethanol (80 mL) was heated at reflux for 2 h. The reaction was then cooled in an ice bath, and water (10 mL) was added with stirring. The resultant precipitate was collected by filtration to afford the desired product as pale crystals. LC/MS 272.7 (M+1).
