YieldReaction ConditionsOperation in experiment
1138 mg at 90℃; for 2.5 h; Step 2: A stirred mixture of methyl 5,6-diaminonicotinate (1.69 g, 10.12 mmol) from Step 1 of this Example,formic acid (0.5 mL), and triethylorthoformate (25 mL) was heated at 90 °C for 2.5 h. The reaction mixture was cooledto rt and then the precipitated solid was collected by filtration and dried to afford methyl 3H-imidazo[4,5-b]pyridine-6-carboxylate (588 mg, 33percent) as a cream solid which did not require further purification. The filtrate was concentratedunder reduced pressure, and the residue purified by silica gel flash chromatography eluting with 100percent DCM to 10percentMeOH in DCM to afford additional methyl 3H-imidazo[4,5-b]pyridine-6-carboxylate (550 mg, 31percent) as a cream solid. 1HNMR (300 MHz, DMSO-d6) δ 13.33 (br s, 1H), 8.95 (d, J = 1.5 Hz, 1H), 8.64 (s, 1H), 8.50 (d, J = 1.5 Hz, 1H), 3.91 (s,3H).
