Versuchsvorschrift

To a solution of (R)-tert-butyl(1-(2-(1-ethyl-1H-pyrrolo[2,3-b]pyridin-2-yl)-7-methoxy-1-methyl-1H-benzo[d]imidazole-5-carbonyl)piperidin-3-yl)carbamate (4.4 g, 8.26 mmol) in dichloromethane (DCM) (20 ml) was added TFA (9 ml, 118 mmol) dropwise. The reaction mixture was stirred for 1 hour 30 minutes. LC/MS showed that that desired product had formed with no starting material remaining. The reaction mixture was concentrated under vacuum to afford an oil. The oil was dissolved in methanol and split into two equal batches and passed through two separate 70 g SCX cartridges. The columns were washed with MeOH (2CV) and the product collected from both columns as the free base with 2M ammonia in methanol (3CV). The product was concentrated under vacuo and dried under vacuum to afford the title compound as a white solid (3.46 g).
