Reaction Steps

starting from tert-butyl (1S,4S)-5-[(5-amino-1-benzofuran-7-yl)methyl]-2,5-diazabicyclo[2.2.1]heptane-2-carboxylate (44 mg crude starting material, 0.10 mmol; obtained in Example 118, Step 2) and o-toluenesulfonyl chloride (22 μL, 0.15 mmol). The title compound (15 mg, 31%) was obtained as an off-white solid.
