Reaction Steps

(2-Pyrrolidin-1-yl-cyclobutyl)-carbamic acid benzyl ester (intermediate AA, 475 mg, 1.7 mmol) was dissolved in 25 mL methanol and 4N HCl in dioxane (870 mL, 3.4 mmol) and palladium on charcoal (10%, 184 mg, 0.17 mmol) were added. The reaction mixture was hydrogenated at room temperature with a H2-balloon over night. The palladium on charcoal was filtered off and the solvent was evaporated. The crude product was used without any further purification, light yellow semisolid (525 mg, 99%). The 2 diastereomers were not separated.
