In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 51762-67-5 as follows. Recommanded Product: 51762-67-5
3-nitrophthalonitrile (0.500 g, 2.888 mmol) was dissolved in anhydrous dimethylformamide (75 mL) under Ar and hydroxymethyl-EDOT (0.500 g, 2.903 mmol) was added. After stirring for 10 min, finely ground anhydrous K2CO3 (1.200 g, 8.682 mmol) was added in portions over 2 h with efficient stirring. The reaction mixture was stirred at room temperature for 120 h under Ar. Then the solution was poured into ice-water. The resulting white solid was collected by filtration and washed first with water and then with hexane. Yield 0.493 g (57%). Mp: 192 C. FT-IR: numax, cm-1 3116.56 (CH, aromatic), 2963.20 (CH, aliphatic), 2230.15 (C?N). 1H NMR (400 MHz, DMSO-d6, 298 K): delta, ppm 7.88-7.69 (3H, benzene -CH), 6.64 (2H, thiophene -CH), 4.63-4.13 (5H, -CH and -CH2). 13C NMR (400 MHz, CDCl3, 298 K): delta, ppm 160.38, 141.00, 140.83, 135.87, 126.21, 118.72, 115.71, 115.35, 113.48, 103.10, 100.16, 71.49, 68.00, 64.77. GC-MS: m/z 298 [M]+. C15H10N2O3S (298.04): calcd. C 60.39, H 3.38, N 9.39; found C 60.37, H 3.37, N 9.40.
