Reaction Steps

tert-butyl 4-[4-[5-amino-6-(6-methyl-1H-benzimidazol-2-yl)pyrazin-2-yl]benzoyl]-1,4-diazepane-1-carboxylate (117 mg, 0.2218 mmol) was dissolved in DCM (3 mL) and the mixture was cooled to 0° C. TFA (3 mL, 38.94 mmol) was added and the reaction mixture was allowed to warm to room temperature and stirred for a further 2 hours. Solvents were evaporated and the residue was dissolved in a mixture of MeCN and water (5 mL/5 mL) and submitted to Genevac evaporation to yield the product (119 mg, 99% Yield).
