合成路线1
该中间体在本合成路线中的序号:(I)The methylation of 1,6-naphthalenediol (I) with dimethyl sulfate gives 1,6-dimethoxynaphthalene (II), which by reaction with sodium-ethanol is converted to 5-methoxy-2-tetralone (III). The condensation of (III) with propylamine - p-toluenesulfonic acid and subsequent hydrogenation with H2 over Pt affords 5-methoxy-N-propyl-1,2,3,4-tetrahydronaphthalen-2-amine (IV). which is demethylated with HBr to 5-hydroxy-N-propyl-1,2,3,4-tetrahydronaphthalen-2-amine (V). Finally, this compound is reductively alkytated with 2-thienylacetic acid (VI) using boranetrimethylamine complex to yield N-0437.
