Sodium Bicarbonate → HCID 66812945, compound

Participants

Reaction Steps

To a solution of dimethyl 6-cyanopyridine-2,3-dicarboxylate from Step A (13.0 g, 59.0 mmol) in EtOH (295 mL) was added lithium borohydride (29.5 mL of a 2 M solution in THF, 59.0 mmol) dropwise. The reaction mixture was stirred at ambient temperature for 4 h, and then cooled to 0° C. Saturated aqueous NaHCO3 (200 mL) was added slowly and the quenched mixture was extracted with EtOAc (9×100 mL). The combined organic extracts were dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by silica gel chromatography, eluting with a gradient of CH2Cl2:MeOH—100:0 to 85:15, to give the title compound. MS: m/z=165 (M+1).
