実験手順

4-Chloro-3-ethyl-1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridine-5-carbaldehyde (1.48 g, 4.05 mmol) in 1,4-dioxane (15 mL) was treated with HCl (4.0 N in 1,4-dioxane, 2.0 mL, 8.1 mmol) then the mixture was stirred for about 16 h at rt. The solvents were evaporated then the material was suspended in Et2O (15 mL) then the solids were collected by filtration and dried under reduced pressure overnight to give 4-chloro-3-ethyl-1H-pyrrolo[2,3-b]pyridine-5-carbaldehyde (0.762 g, 90%): LC/MS (Table 2, Method a) Rt=2.21 min; MS m/z 209 (M+H)+.
