66% | Thieno[2,3-b]pyridine-2-carbaldehyde: In an atmosphere of argon a mixture of 1.3 mL (2.08 mmol) of 0.8 M n-butyllithium in hexane and 0.3 mL (3.3 mmol) of N,N,N?,N?-tetramethylethylenediamine was stirred magnetically at room temperature for 30 minutes, diluted with 5 mL of hexane, cooled in a bath of dry ice-ethanol, and treated (with vigorous stirring) dropwise (from a syringe with a small needle) with 0.23 g (1.7 mmol) of thieno[2,3-b] pyridine. The mixture was stirred in the bath for 7 h longer and then for 12 h while it warmed to room temperature. It was cooled in ice, treated with 0.15 g (2.1 mmol) of dimethylformamide, stirred for one hour, and then treated successively with 1 mL of ethanol, 3 mL of saturated aqueous ammonium chloride solution, and 4 mL of water. The layers were separated. The organic layer (plus chloroform extracts of the aqueous layer) was dried (magnesium sulfate) and evaporated. The residue was triturated with hexane to give 0.18 g (66%) of brown solid; m.p. 131.5-132.5 C. Recrystallizations from ethanol (once with charcoal) gave white needles. 1H NMR (300 MHz, CDCl3) ppm 7.41 (dd, J = 4.5 Hz, 8.1 Hz, 1 H), 7.99 (s, 1 H), 8.24 (dd, J = 1.8 Hz, 8.1 Hz, 1 H), 8.73 (dd, J = 1.8 Hz, 4.5 Hz, 1 H), 10.12 (s, 1 H). 13C NMR (75 MHz, CDCl3) ppm 120.7, 131.8, 132.3, 134.0, 143.2, 150.5, 163.8, 185.0.

With sodium borohydrid; In ethanol; | EXAMPLE N 2-Chloromethyl-thieno[2,3-b]pyridine Thieno[2,3-b]pyridine-2-carboxaldehyde (1.63 g) prepared according to J. Het. Chem. 355 (1974) was dissolved in ethanol (20 ml) and to the solution was added sodium borohydride (0.19 g). After 30 minutes the solution was evaporated to dryness and the residue extracted with methylene chloride (50 ml). The organic extract was washed with water (2*25 ml), the extract dried and then evaporated to obtain 2-hydroxymethylthieno[2,3-b]pyridine (1.40 g) as an amber oil.

With Montmorillonite K 10; In toluene; for 5h;Reflux; | A 100 mL round-bottomed flask was charged with thieno[2,3-b]pyridine- 2-carbaldehyde (1.0 g, 6.1 mmol, Maybridge, Tintagel, United Kingdom), 3,4- dihydro-2H-l,5-benzodioxepine-7-sulfonamide (1.4 g, 6.1 mmol, Enamine, Kiev, Ukraine), Montmorillonite K 10 (1.4 g, Sigma- Aldrich, St. Louis, MO), and toluene (31 mL), fitted with a Dean-Stark trap and a reflux condenser, and then the reaction mixture was heated at reflux for 5 h. After that time, the reaction mixture was filtered, the filtrate was allowed to cool to room temperature, filtered, and the filter cake was collected to give N-(thieno[2,3-b]pyridin-2- ylmethylidene)-3,4-dihydro-2H-l,5-benzodioxepine-7-sulfonamide (1.1 g) as pale, peach-colored solid. |
