How is 3-Methoxy-O-methyltyrosine (CAS: 32161-30-1) typically synthesized?

3-Methoxy-O-methyltyrosine can be synthesized via a series of reactions starting from tyrosine. The key steps include methylation of the hydroxyl group and subsequent esterification of the phenolic hydroxyl group. Common reagents used include methanol and methanol sodium, with sodium hydroxide as a catalyst. The synthetic route ensures high yield and selectivity, making it suitable for commercial-scale production.
