To synthesize S(?)2-(N-propylamino)-5-methoxytetralin, the key chiral intermediate of rotigotine. Methods 5-Methoxy-2-tetralone was used as the starting material, amination with propylamine, catalytic hydrogenation by 10% palladium carbon, and chiral separation were carried out and the key chiral intermediate was obtained. Results The overall yield of S(?)2-(N-propylamino)-5-methoxytetralin was 21.5%. Conclusion The synthetic route and the key chiral intermediate of rotigotin have the characteristics of inexpensive, high yield, and suitable for industrial production of S(?)2-(N-propylamino)-5-methoxytetralin.
