合成路线1
该中间体在本合成路线中的序号:(IX)In a related process, the racemic piperidinyl ketone (VII) was initially resolved employing D-tartaric acid. The target (2S)-piperidinyl propanone (VIII) was then diastereoselectively reduced to the (1S,2S)-alcohol (IX) employing LiBH4 in EtOH. Finally, debenzylation of (IX) by catalytic hydrogenolysis yielded the title compound

该中间体在本合成路线中的序号:(IX)In a related process, the racemic piperidinyl ketone (VIII) was initially resolved employing D-tartaric acid and then subjected to a diastereoselective reduction to the (1S,2S)-alcohol (IX) employing LiBH4 in EtOH. Finally, debenzylation of (IX) by catalytic hydrogenolysis with Pd/C in EtOH and methanesulfonic acid, followed by addition of water, yielded the title compound
