实验过程

A mixture of 2-methylene-3-quinuclidinone dihydrate hydrochloride (27.2 g, 0.13 mol, 1 eq) and K2CO3 (86.0 g, 0.62 mol, 4.8 eq) is dissolved in 130 mL water and 250 mL CH2Cl2 and stirred vigorously. After 3 days, the layers are separated and the aqueous layer is extracted with CH2Cl2. The combined organic layers are dried (MgSO4), filtered and concentrated to give 17.8 g (100%) of 2-methylenequinuclidin3-one as a yellow oil. MS (ESI) for C8H11NO m/z 138.1 (M+).
