YieldReaction ConditionsOperation in experiment
With sodium methylate; In methanol; water; sodium thiomethoxide; REFERENCE EXAMPLE 44 A solution of sodium methoxide in methanol (82.65 ML; 1 M) is added slowly to a stirred solution of <strong>[59237-53-5]methyl 6-chloro-5-nitronicotinate</strong> (17 g) in anhydrous methanol (250 ML) and the mixture is stirred for 8 hours. The mixture is concentrated, and the residue is treated with water and extracted with ethyl acetate. The extract is washed with water, treated with decolourising charcoal, and dried over magnesium sulphate. Concentration gives methyl 6-methoxy-5-nitronicotinate (9.8 g), in the form of an orange solid. Recrystallization from cyclohexane gives white needles, m.p.118-119°C. By proceeding in a similar manner using sodium thiomethoxide instead of sodium methoxide as the starting material, there is prepared methyl 6-methylthio-5-nitronicotinate.

In dichloromethane; at 0℃; To a suspension of 49.0 g (0.27 mol) 6-hydroxy-5-nitro-nicouenic acid in thionyl chloride (240 mi) are added 2 ml of DMF. This mixture is stirred at 60°C until the evolution of gaz has ended. Then it is stirred at 80°C for further 18 h. Residual thionyl chloride is removed under vacuo and the resulting residue is coevaporated three times with toluene. Subsequently this reaction mixture is dissolved in dichloromethane (100 mi) and cooled to 0°C before methanol (55.5 ml) is dropwise added. The precipitated solid is filtered off and dried under vacuo at 50°C to give 27.6 g (13.7 mmol/52 percent) of the title compound as a light yellow solid with a melting point of 78°C (dichloromethane/methanol).

After distilling off the solvent under reduced pressure, dilute hydrochloric acid was added to the residue followed by extraction with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure. Diisopropyl ether was added to the residue and the crystals thus precipitated were taken up by filtration to thereby give 24.7 g of the title compound as yellow crystals. 1H-NMR(DMSO-d6) delta ppm: 3.78(s, 3H),5.91-6.00(br.s, 2H), 7.12(d, J=2.0 Hz, 1H), 7.53(dd, J=2.0, 6.4 Hz, 1H)
