YieldReaction ConditionsOperation in experiment
With thionyl chloride In toluene for 2h; Heating / reflux; 1A 3-Quinuclidinecarbonyl chloride hydrochloride EXAMPLE 1A 3-Quinuclidinecarbonyl chloride Hydrochloride 3-Quinuclidinecarboxylic acid hydrochloride was prepared as described by Orlek et al. J. Med. Chem. 1991, 34, 2726. 500 mg (2.61 mmol) of 3-quinuclidinecarboxylic acid are heated together with 1.9 ml (26.09 mmol) of thionyl choride under reflux for 2 h. The reaction mixture is freed of excess thionyl chloride under reduced pressure. 20 ml portions of toluene are added twice and evaporated to dryness each time. The product obtained in this way is reacted immediately without further purification.

YieldReaction ConditionsOperation in experiment
76% With lithium aluminium tetrahydride In tetrahydrofuran; diethyl ether at 20℃; for 73h; Inert atmosphere; Cooling with ice; A solution of quinuclidine-3-carboxylic acid (665 mg, 4.28 mmol) in dry THF (7 mL) was stirred under N2 and cooled in an ice-water bath. A 2 M solution of LiA1H4 in Et20 (4.3 mL, 8.56 mmol) was added dropwise over a period of 10 minutes. The mixture was stirred in an ice bath for one hour then allowed to warm to room temperature and stirred for 72 hours. The mixture was cooled in an ice-bath and a 1 N solution of NaOH (1 mL) was added dropwise over a period of 10 minutes followed by water (0.5 mL). The mixture was stirred at room temperature for one hour and then filtered through a Celite cartridge which was then washed through with a small amount of THF and water. The combinedfiltrates were concentrated in vacuo to give a racemic mixture of the title product as a colourless oil. (792 mg, 76%).LCMS (Method 2): [MH+] = 142 at 0.60 mm.

LCMS (Method 2): [MH+] = 142 at 0.60 min.Purification of the mixture of enantiomers by chiral preparative SFC afforded the single enantiomers Title compound (Intermediate 3, single enantiomer 1) was obtained as a light brown gum (235 mg, 59%). LCMS (Method 4): [MH+] = 142 at 0.62 min. Chiral analysis (Method 5) at 9.56 min. [a] = -51.17 0 (c = 0.3 g/100 mL, CH3OH).Title compound (Intermediate 4, single enantiomer 2) was obtained as a light brown gum (203 mg, 51%). LCMS (Method 4): [MH+] = 142 at 0.61 min. Chiral analysis (Method 5) at 1 1.28 min. [a]2D° = +36.33 0 (c = 0.3 g/100 mL, CH3OH).
