processo de resolução de n-[2-(1,6,7,8-tetra-hidro-2h-indeno[5, 4- b]furano-8-il)]etilamina e ramelteon

摘要

Disclosed herein is a process for resolving N-[2-(1,6,7,8-tetrahydro-2H-indeno [5,4-b] furan-8-yl)] ethylamine into its isomers using an optically active acid and a process for preparing ramelteon from the resolved isomer.
