Reaction Steps

4,5-Dichloro-3-nitro-pyridin-2-ylamine (1.01 g, 4.86 mmol) and (1S,2S,3R,4R)-3-Amino-bicyclo[2.2.1]hept-5-ene-2-carboxylic acid amide trifluoroacetic acid salt (1.5 g, 5.5 mmol) were combined with N,N-diisopropylethylamine (3.3 g, 26 mmol) in isopropanol (15 mL) and heated at 60° C. overnight. The reaction was permitted to cool to room temperature and the orange solid which had formed was isolated by filtration. The solid was washed with 3 mL cold isopropanol and was dried in an air stream to afford 1.493 g (95%) of the desired product.
