With ammonia; 3,5-pyridine-dicarboxamide is made from the action of NH3 on dimethyl- pyridine-3,5-dicarboxylate. This diamide is quaternarized with dimetyl sulfate and treated with a solution of cyanogen bromide in acetonitile in the presence of imidazole. The result is the imidazolium salt of N,N'-dicyano-1-methyl-pyridinium-3,5dicarboxamide.

YieldReaction ConditionsOperation in experiment
With potassium hydroxide; In methanol; at 20℃; for 16h; A solution of potassium hydroxide (1.30 g, 23.2 mmol.) in MeOH (25 mL) was added carefully to a solution of <strong>[4591-55-3]pyridine-3,5-dicarboxylic acid dimethyl ester</strong> (4.53 g, 23.2 mmol.) in MeOH (50 mL). The reaction mixture was stirred at room temperature for 16 h. Diethyl ether (600 mL) was added, the reaction was filtered, and the precipitate was suspended in MeOH (20 mL). Concentrated HCl (75 mL) was added followed by ditheyl ether (120 mL). Filtration of the resulting mixture yielded the ester/acid as the hydrochloride salt (3.23 g, 14.9 mmol., 64%) which was used without further purification. The ester/acid (1.0 g, 4.61 mmol.) was suspended in toluene and thionyl chloride (1.33 mL, 18.44 mmol.) was added. The reaction was heated to reflux for 4 h, then concentrated without heating the reaction flask above 50 C. The crude acid chloride was dried in vacuo and used directly in the next step. Lithium tri-tertbutoxyaluminum hydride (1M, 3.58 mL, 3.58 mmol.) was added to a solution of acid chloride (841 mg, 3.58 mmol.) in THF (10 mL) at -78 C. The reaction was allowed to warm to room temperature, was stirred for 16 h, and was quenched with 1N HCl. The resulting solution was concentrated, was partitioned between ethyl acetate and saturated sodium bicarbonate was extracted with ethyl acetate (3×). The combined organic extracts were dried with MgSO4 and concentrated. The crude alcohol was purified by column chromatography (70% ethyl acetate/hexane) to yield pure product (200 mg, 1.20 mmol., 26%). 1H NMR (DMSO-d6): delta=8.97 (s, 1H), 8.75 (s, 1H), 8.24 (s, 1H), 5.48 (t, J=6 Hz, 1H), 4.62 (d, J=6 Hz, 3H), 3.89 (s, 3H). Calculated mass=165.1, [M+H]+=168. HPLC (method D) rt=3.4 min ( 98%).

YieldReaction ConditionsOperation in experiment
With sodium hydrogencarbonate; In water; Step 2: Dimethyl pyridine-3,5-dicarboxylate 1 -oxide; Dimethyl pyridine-3,5-dicarboxyIate hydrochloride was treated with saturated aqueous sodium bicarbonate. The mixture was extracted with DCM and the organic layer concentrated to afford the free base, dimethyl pyridine-355-dicarboxylate5 as a white solid. This solid (5.Og, 25.6 mmol) was dissolved in DCM (150 mL) and the solution cooled to 0 0C and treated with urea hydrogen peroxide (5.06 g, 53.8 mmol) followed by trifluoroacetic anhydride (7.2 mL, 51.2 mmol). The reaction mixture was stirred at room temperature overnight and was then treated with additional urea hydrogen peroxide (2.0 g, 21.3 mmol) and trifluoroacetic anhydride (3.1 mL, 22 mmol). The mixture was stirred at room temperature for an additional 3 hours and was then quenched by addition of aqueous sodium dithionite and stirred for 15 minutes. The mixture was then poured into 1 N aqueous HCl and extracted with DCM. The combined organic extracts were dried, filtered and concentrated. The residue was purified by SCG (0-5% MeOH/DCM) to give the title compound as a light yellow solid. 1H TSlMR (400 MHz, d6-DMSO, ppm): delta 8.73 (m, 2H)3 8.08 (m, IH), and 3.92 (s, 6H). ES MS: m/z = 212 (M+l).
