실험 절차
To a solution of 1 g (3.784 mmol) 5-(2-Methoxy-ethoxy)-1H-pyrrolo[2,3-c]pyridine-2-carboxylic acid ethyl ester (example 10 (iii)) in 50 mL THF and 25 mL MeOH 15.14 mL of a 1M LiOH solution were added. The mixture was stirred for 2 h at room temperature. The organic solvents were removed in vacuo, the solution acidified and concentrated in vacuo. The residue was purified by flash chromatography over silica gel using H2Cl2/MeOH/HOAc/H2O=90/10/1/1 as eluent. The product fractions were combined, concentrated in vacuo and lyophilized.
