Procedure

To a solution of 4,5,7,8-tetrahydro-imidazo[4,5-d]azepine-1,6-dicarboxylic acid di-tert-butyl ester (Preparation 26, 6.87 g, 20.37 mmol) in methanol (60 mL) was added an aqueous 1M solution of sodium hydroxide (40.7 mL, 40.7 mmol). The resulting mixture was stirred at room temperature for 2 hours and then concentrated in vacuo. The residue was partitioned between DCM (100 mL) and water (100 mL). The organic layer was dried over MgSO4 and concentrated in vacuo to give the title compound as a brown foam (4.8 g) in a 99% yield.
