5381-20-4, Thianaphthene-3-carboxaldehyde is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
5381-20-4, Thianaphthene-3-carboxaldehyde (5 g, 30.8 mmol) was dissolved in anhydrous ethanol (50 mL). Sulfamide (12.22 g, 123.30 mmoles) and sulfamic acid (0.29 g, 3.08 mmoles) were added and the reaction mixture heated to 45 C. for 18 h. The reaction mixture was then cooled to room temperature. Sodium borohydride (1.2 g, 30.8 mmol) was added and the reaction mixture was stirred for 1 hour. 1 N HCl (30 mL, 30 mmol) was added and the reaction mixture was filtered through Celite. The filtered solution was then diluted with water (100 mL). The precipitate was filtered to yield the title compound as a off white solid. 1H NMR (DMSO-d6): delta 7.98 (1H, dd, J=6.5, 2.3 Hz), 7.92 (1H, dd, J=6.6, 2.4 Hz), 7.62 (1H, s), 7.36-7.45 (2H, m), 7.08 (1H, t, J=6.3 Hz), 6.72 (2H, s), 4.31 (2H, d, J=6.3 Hz)
The synthetic route of 5381-20-4 has been constantly updated, and we look forward to future research findings.
