Versuchsvorschrift

A mixture of methyl 2-(5-(4-amino-4-methylpentyloxy)-1-methyl-1H-indazol-3-yl)-5-trityl-5H-pyrrolo[3,2-b]pyrazine-7-carboxylate (100 mg, 0.15 mmol), potassium hydroxide (280 mg, 5 mmol) in 2.5 mL of water and 5 mL of 1,4-dioxane was heated to reflux for 90 min. The reaction mixture was cooled to room temperature, solvent evaporated, the residue diluted with H2O (25 mL) and the mixture acidified with 1N HCl to pH=7. The residue was extracted with EtOAc (100 mL). The organic layer was washed with H2O (100 mL), brine (100 mL), dried over Na2SO4 and concentrated under reduced pressure to give 2-(5-(4-Amino-4-methylpentyloxy)-1-methyl-1H-indazol-3-yl)-5-trityl-5H-pyrrolo[3,2-b]pyrazine-7-carboxylic acid as yellow solid (100 mg, >100%) which was used to next step without further purification. LCMS: (M+H)+=651.
