Budipine (brand name Parkinsan) is an antiparkinson agent marketed for the treatment of Parkinson's disease.[2][3][4]

While its exact mechanism of action is not well characterized,[2] it is believed to be an NMDA receptor antagonist,[5][6] but also promoting the synthesis of dopamine.[7]

Because it provides additional benefits relative to existing treatments, it probably does not precisely mimic the mechanism of an existing known treatment.[7][8]


Budipine can be prepared from the 1-tert-butyl-4-piperidone [1465-76-5] directly by treatment with benzene in the presence triflic acid.[9] This method of synthesis enables a 99% yield of product.

4-Phenyl-1-t-butyl-4-piperidinol,[11] (1)

1-t-butyl-3-benzoyl-4-phenyl-4-piperidinol [81831-81-4] (3)
