실험 절차

To a solution of ethyl 4-(tert-butoxycarbonyl(2,4-dimethoxybenzyl)amino)-6-ethyl-1-methyl-1,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridine-7-carboxylate (example 1G, 5.32 g, 9.9 mmol) in ethanol (49.5 mL) was added 1 N NaOH aqueous solution (49.5 mL). The reaction mixture was heated at 60° C. 3 h and cooled to rt. Ethanol was removed by concentration in vacuo. The residue was acidified with 1 N HCl and the product was collected by vacuum filtration. 4-(tert-Butoxycarbonyl(2,4-dimethoxybenzyl)amino)-6-ethyl-1-methyl-1,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridine-7-carboxylic acid (4.3 g, 8.44 mmol, 85% yield over two steps) was isolated as a white solid after drying on the vacuum.
