Reaction Steps

Under argon, pyruvic acid (6.90 ml, 100.1 mmol) and 1,4-diazabicyclo[2.2.2]octane (11.2 g, 100.1 mmol) were added to a solution of methyl 6-amino-5-iodo-2-methylnicotinate (9.00 g, 30.8 mmol) in N,N-dimethylformamide (88 ml), and the flask was evacuated and flushed with argon. Argon was subsequently passed through the solution for 5 min, palladium(II) acetate (0.345 g, 1.54 mmol) was then added and the mixture was heated at 100° C. for 2 h. The cooled solution was filtered through Celite and the dimethylformamide was distilled off. The residue was then taken up in water and acidified with hydrochloric acid, giving a solid (6.3 g, 86% of theory). HPLC-MS: log P=1.26; mass (m/z): 235.0 (M+H)+; 1H-NMR (DMSO) 2.79 (s, 3H), 3.85 (s, 3H), 7.19 (s, 1H), 8.62 (s, 1H), 12.50 (s, 1H).
