Reaction Steps

A 10M solution of Methylamine in H2O (30.0 mL, 386 mmol) was added to a stainless steel reactor containing 3-amino-6-bromopyridine-2-carboxylic acid ethyl ester (Compound 6E, 7.614 g, 31.07 mmol) in MeOH (20.0 mL). The reactor was sealed and heated to 100° C. for 16 hours. The cooled reaction mixture was transferred to a round bottom flask and concentrated in vacuo forming a yellow precipitate which was collected by filtration. Further precipitate formed in the filtrate which was also collected. The combined precipitates were dried in vacuo to afford the title compound as 6.18 g of a yellow solid. 1H NMR (400 MHz, CDCl3) δ 7.80 (br. s., 1H), 7.27 (d, J=8.6 Hz, 1H), 6.91 (d, J=8.6 Hz, 1H), 6.02 (br. s., 2H), 2.97 (d, J=5.1 Hz, 3H).
