摘要: Provided is a production method for a cis-QMF, which has a low environmental burden and is industrially advantageous. Specifically provided is a production method for a cis-type 2-alkylspiro(1,3-oxathiolane-5,3′)quinuclidine hydrochloride, including: reacting a cis-trans isomer mixture of 2-alkylspiro(1,3-oxathiolane-5,3′)quinuclidine with p-nitrobenzoic acid; resolving the resultant product to produce a cis-type 2-alkylspiro(1,3-oxathiolane-5,3′)quinuclidine p-nitrobenzoate; and converting the p-nitrobenzoate into a hydrochloride.
