Reaction Steps

A solution of benzyl 2-isopropylsulfonyl-2,6-diazaspiro[3.4]octane-6-carboxylate (230 mg, 0.65 mmol) in AcOH (2 mL) was treated with Pd (7.0 mg, 0.06 mmol) (10% on activated carbon) and stirred under an atmosphere of hydrogen for 1.5 h. The reaction mixture was diluted with DCM, filtered and washed with 1N HCl and brine. The organic layer was dried over Na2SO4, filtered and concentrated to obtain 2-isopropylsulfonyl-2,6-diazaspiro[3.4]octane in quantitative yield. LC/MS m/z 219.3 [M+H]+.
