〖合成方法〗Etilevodopa has been obtained by several different methods: (i) esterification of 3-hydroxy-L-tyrosine (I) (L-DOPA) with ethanol catalyzed by dry HCl gas; (ii) esterification of 3-hydroxy-L-tyrosine (I) (L-DOPA) by means of SOCl2 in hot ethanol; (iii) enzymatic hydroxylation of L-tyrosine ethyl ester (II) by means of mushroom tyrosinase in a phosphate buffer.
