Chemical compound

SKF-89976A is an anticonvulsant, acting as a GABA reuptake inhibitor via blockade of GAT-1.^[1]

Synthesis

Ex 1: Finkelstein Sn2 alkylation between 1,1-Diphenyl-4-bromobutene [6078-95-1] (1) & Ethyl nipecotate [5006-62-2] (2) gives [89203-62-3] (3). Optional saponification of the ester group gives the title amino-acid compound (4).
