Methanol → methyl (1S,3R)-3-aminocyclopentane-1-carboxylate hydrochloride

Participants

Reaction Steps

(1S,3R)-3-aminocyclopentane-1-carboxylic acid (Acros; 952 mg, 7.37 mmol) was suspended in MeOH (15 ml) and cooled in an acetone/ice bath. Thionyl chloride (1.11 mL, 14.74 mmol) was added dropwise and the resulting pale yellow solution stirred in the acetone/ice bath for 30 minutes and then allowed to warm to room temperature, stirred at room temperature for 1 hr then heated at reflux for 1 hr. Solvents were evaporated to give the title compound as a cream solid after drying under high vacuum. (1.32 g 100%)
