Procedure

A mixture of 7-({2-[(2,3-dihydro-1H-pyrrolo[2,3-b]pyridin-4-ylmethyl)-amino]-pyridine-3-carbonyl}-amino)-4,4-dimethyl-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester (0.070 g), HCl (4N, 3.0 mL) and dioxane (4.0 mL) was stirred at RT for overnight. Sat'd NaHCO3 was added until the bubbling stopped. The aqueous phase was extracted with CH2Cl2 3 times. The combined organic phases were dried over Na2SO4 and evaporated to yield a tan colored residue as a crude product, which was chromatographed through HPLC. The fractions were collected and the solvent was evaporated. The residue was treated with NaHCO3 and the solvent was evaporated. The residue was washed with H2O to remove any inorganics to afford 2-[(2,3-dihydro-1H-pyrrolo[2,3-b]pyridin-4-ylmethyl)-amino]-N-(4,4-dimethyl-1,2,3,4-tetrahydro-isoquinolin-7-yl)-nicotinamide.
