By the use of probability method, the sol-gel distribution equations including intramolecularreaction of sol are deduced. The theoretical and experimental values are coincident.
Levetiracetam was prepared from L-methionine via reduction-dethiomethylation, esterification, ammonolysis, amidation and intramolecular cyclocondensation reaction with 44.6% overall yield.
