The present invention relates to a method for synthesis of an optically active halopyridyl-azacyclo-pentane derivative and the intermediate thereof which comprises preparing an optically active allene-1,3-dicarboxylic acid ester derivative from an optically active acetonedicarboxylic acid ester derivative and then proceeding through a 7-azabicyclo[2.2.1]heptane derivative to obtain the objective product.
