Procedure
(S)-2-Methyl-propane-2-sulfinic acid [(R)-1-(1-cyano-cyclopentyl)-ethyl]-amide (1.96 g, 8.07 mmol) was dissolved in MeOH (16 mL) and HCl (4.0 M in 1,4-dioxane, 4.0 mL, 16.0 mmol) was added. The reaction mixture was stirred at room temperature for 30 min then concentrated to give 1-((R)-1-amino-ethyl)-cyclopentanecarbonitrile hydrochloride as an off-white solid which was used without further purification.
