Reaction Steps

Scheme IA, step B: (+,−) 2-Phenyl-cyclopentanone oxime from preparation 6 above was dissolved in 35 mL of ethanol and hydrogenated using 90 mg of 5% Pd/C at 40° C. overnight at 413.69 kPa (60 psi). The solution was filtered and concentrated in vacuo to give 0.43 g (62%) of a colorless oil. Some dimeric material resulted by this procedure according to the mass spec. The cis:trans ratio was estimated to be 4:1. The amine was used directly without further purification. The NMR was consistent with the assigned structure.
