A common heterocyclic compound, the quinuclidine compound, name is Quinuclidine-4-carboxylic acid hydrochloride,cas is 40117-63-3, mainly used in chemical industry, its synthesis route is as follows.
Example 1(Quinuclidin-4-yl)methanol (Quinuclidin-4-yl)carboxylic acid was prepared from 4-cyanoquinuclidine (Oakwood Products) following the procedure of Grob and Renk, Helv. Chim. Acta, 37, 1681 (1954).To a stirred suspension of quinuclidine-4-carboxylic acid hydrochloride (100 mg, 0.523 mmol) in 3 mL of anhydrous tetrahydrofuran at 0 C. was added borane methylsulfide complex (42 mg, 0.553 mmol). The mixture was stirred at room temperature for 1 hr and heated to reflux overnight. The reaction was cooled to 0 C. and carefully treated with 1 mL of methanol. The solvent was then removed under reduced pressure to leave the desired alcohol. Yield 36 mg. MS (m/e): 141.
As the rapid development of chemical substances, we look forward to future research findings about 40117-63-3
