Reaction Steps

To a solution of benzyl 2-methyl-6-methylsulfonyl-spiro[3,4-dihydropyrrolo[1,2-a]pyrazine-1,4′-piperidine]-1′-carboxylate (520 mg, 1.25 mmol) in EtOH (13 mL) was added 10% palladium-carbon (66 mg, 0.062 mmol) under nitrogen atmosphere. The reaction mixture was stirred at room temperature for 16 h under a hydrogen atmosphere. The mixture was filtered through a plug of celite and the solvent was evaporated under reduced pressure to yield 2-methyl-6-methylsulfonyl-spiro[3,4-dihydropyrrolo[1,2-a]pyrazine-1,4′-piperidine] (342 mg, 97%) as an off-white solid. ESI-MS m/z calc. 283.1, found 284.3 (M+1)+; Retention time: 0.30 minutes (3 min run).
