A mixture of benzyl 2,2-dimethyl-3-oxocyclopentylcarbamate (950 mg, 3.64 mmol, from Step 1) and 10% palladium on carbon (193 mg) in methanol (20 mL) was stirred under hydrogen (20 psi) for 2 h. After filtration to remove the catalyst, the filtrate was concentrated to give crude 3-amino-2,2-dimethylcyclopentanone (430 mg), which was used in the next reaction without purification.
