Related Products of 153813-70-8, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 153813-70-8, name is 3-Nitroisonicotinaldehyde. This compound has unique chemical properties. The synthetic route is as follows.
To a stirred solution of N-(4-trifluoromethoxyphenyl) 3-aminothiophene-2-carboxamide 3 (302 mg, 1 mmol) in 15 mL ethyl acetate was added 3-nitro pyridine-4-carboxaldehyde 4 (182.4 mg, 1.2 mmol) and trifluoroacetic acid (228 mg, 2 mmol). Sodium borohydride (50 mg,1.3 mmol) was added as a solid over 1 min and the reaction mixture was allowed to stir for 1 h or until the amine was completely consumed as monitored by TLC (n-hexane:EtOAc, 60:40). Sodium hydroxide (10% w/v solution) was added to the reaction mixture to make the solution alkaline (pH 8-9). The phases were allowed to separate and the organic layer was collected, washed with brine, dried over sodium sulfate and concentrated to afford crude yellow product. This crude product was subjected to flash column chromatography (n-hexane:EtOAc, 60:40) to the yield the desired product 5 as a yellow solid (390 mg, 89%). m.p. 130-131 C; TLC (60% n-hexane: 40% EtOAc) Rf = 0.60; 1H NMR (CDCl3, delta ppm): 9.36 (s, 1H, Ar), 8.76-8.77 (d, 1H, J = 5.1, Ar), 8.01-8.04 (br t, 1H, NHCH2), 7.62-7.64 (d, 1H, J= 5.2 Hz, Ar), 7.58-7.60 (d, 2H, J = 8.8 Hz, Ar), 7.26-7.28 (m, 1H, Ar), 7.21-7.23 (d, 2H, J = 8.4 Hz, Ar), 7.12 (br s, 1H, NHCO), 6.48-6.49 (d, 1H, J = 5.4 Hz, Ar), 4.96-4.97 (d, 2H, J = 6.4 Hz, NHCH2); IR (CDCl3, cm-1): 1714, 1363 (-NO2), 1221, 1091, 914, 733, 647; Anal.: Calcd for C18H13F3N4O4S: C, 49.32; H, 2.99; N, 12.78; Found: C, 49.50; H, 3.00; N, 12.81.
