YieldReaction ConditionsOperation in experiment
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. IR (CHCl3, cm-1) 1682 (C=O). MS (EI, 70 eV): m/z [%] = 162[M]+ (100), 134[M-CO]+ (26). HRMS (FAB+) calculated for C8H6NOS [M+1] 164.0170, found 164.0167.

YieldReaction ConditionsOperation in experiment
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. 'H-NMR (CDCl3,60 MHz): 4.9 (s, 1H), 6.3 (s, 1H), 6.9 s, 1H), 7.1 (m, 1H), 7.8 (m, 1H), 8.4 (m, 1H).
