Procedure

Prepared using the same method as for Intermediate I-14, but from from 20.8 g (0.0784 mol) of of 2-oxo-2-thien-2-ylacetic acid (3R)-1-azabicyclo[2.2.2]oct-3-yl ester and cyclopentylmagnesium cloride, 0.08 mol (40 ml of a solution 2M in ether). The oil obtained (15.64 g) was purified by chromatography on silica gel eluting with chloroform/methanol/ammonia 97:3:0.5 to obtain 8.38 g (32%) of a pure product, mixture of diastereomers: I-15a and I-15b. Structure confirmed by 1H-NMR.
