With hydrogenchloride; triethylamine;palladium; In ethanol; dichloromethane; toluene; | Preparation 112 Ethyl 2-[(tert-butoxycarbonyl)amino]methyl}isonicotinate To a stirred solution of <strong>[58481-14-4]ethyl 2-cyanoisonicotinate</strong> (2.00 g, 110 mmol, J. Med. Chem., 1976,19, 483) in ethanol (20 ml) was added 2M aqueous hydrochloric acid solution (7.5 ml) followed by 5% palladium on carbon (200 mg). The reaction mixture was stirred at room temperature under a hydrogen atmosphere (60 psi) for 48 hours. The mixture was filtered through arbocel and the filtrate was concentrated under reduced pressure. The residue was dried by azeotropic distillation using toluene under reduced pressure. To a stirred solution of the residue (3.00 g) in dichloromethane (22 ml) was added triethylamine (4.6 ml, 33 mmol) followed by di-tert-butyl dicarbonate (2.62 g, 12.0 mmol). After stirring for 1 hour at room temperature the reaction mixture was diluted with dichloromethane (100 ml) and washed with water (50 ml). The organic component was washed with brine (50 ml), dried over magnesium sulphate and concentrated under reduced pressure to give a brown oily solid. The crude product mixture was purified by flash chromatography on silica gel eluding with dichloromethane:methanol:0.88 ammonia (98:2:0.2 then 97:3:0.3, by volume) to provide the title compound (2.20 g) as a yellow oil. 1H NMR (400 MHz, CDCl3): delta=1.38 (t, 3H), 1.45 (s, 9H), 4.38 (q, 2H), 4.50 (m, 2H), 5.50 (broad s, 1H), 7.73 (d, 1H), 7.81 (s, 1H), 8.65 (d, 1H).

85% | With N,N-Dimethylcarbamoyl chloride; In toluene; for 2.0h;Reflux; Inert atmosphere; | A reaction mixture of 4-(ethoxycarbonyl)pyridine-1-oxide28 (3.64 g, 21.82 mmol), DMCC (3.01 mL, 32.73 mmol) and Zn(CN)2(3.84 g, 32.73 mmol) in toluene (40 mL) was heated under reflux under an argon atmosphere for 2 h. The reaction mixture was cooled to room temperature and H2O (30 mL) was added, and stirring was continued for 15 min. The organic layer was separated, washed with brine, dried over MgSO4 and concentrated under reduced pressure to yield a brown solid. This was then passed through a silica plug using EtOAc:Pet. Ether in a 2:1 ratio as the eluent yielding a yellow oil which solidified on ice. Orange solid (3.28 g, 85%). m.p. 39-40 C (lit. 42-44 C);14 numax (KBr) 2988, 2964, 2238, 1728, 1597, 1557, 1470, 1402, 1393, 1370, 1298, 1281, 1202, 1113, 1015, 990, 918, 890, 862, 763, 686 cm-1; deltaH (300 MHz, CDCl3) 8.90 (1 H, dd, J 4.9, 0.9 Hz, pyr-H), 8.25 (1 H, dd, J 1.5, 0.9 Hz, pyr-H), 8.10 (1 H, dd, J 4.9, 1.5 Hz, pyr-H), 4.47 (2 H, q, J 7.1 Hz, OCH2), 1.44 (3 H, t, J 7.1 Hz, CH3); deltaC (75 MHz, CDCl3) 163.1 (C=O), 151.9, 139.0, 134.7, 127.6, 126.1, 116.6 (CN), 62.6 (OCH2), 14.1 (CH3); HRMS (ESI): [M+H]+, found 177.0659.

62% | With sodium azide; ammonium chloride; lithium chloride; In N,N-dimethyl-formamide; at 110℃; for 12.0h; | Compound 1B (2.28 g, 12.93 mmol), NaN3 (0.93 g, 14.22 mmol), NH4Cl (0.76 g, 14.22 mmol) and LiCl (0.27 g, 6.47 mmol) were heated at 110 C in DMF (20 mL) for 12 h. The reaction mixture was cooled to room temperature, filtered and the filtrate was concentrated under reduced pressure. The remaining residue was redissolved in deionised H2O and 1 M HCl was added dropwise until precipitation was initiated. When the formation of a precipitate ceased, the mixture was filtered. The collected precipitate was recrystallised from hot EtOH, yielding white crystals which were filtered off and washed with cold EtOH.
