A practical synthetic route to pimavanserin tartrate, I in which the target compound was obtained with 99.84% purity and in 46% total yield via a 5-step synthesis starting from 4-hydroxybenzaldehyde and (4-fluorophenyl)methanamine, was reported. The main advantages of the route included inexpensive starting materials, mild reaction conditions and an acceptable overall yield.1-Methyl-4-piperidone(cas: 1445-73-4COA of Formula: C6H11NO) was used in this study.
1-Methyl-4-piperidone(cas: 1445-73-4) is a member of piperidine. Piperidine is a key saturated heterocyclic scaffold found in several of the top-selling small molecule pharmaceuticals and natural alkaloids, with a diverse range of biological activities. Hence, continuous efforts have been made to develop convenient methods to prepare piperidine derivatives.COA of Formula: C6H11NO
