Procedure
To a refluxing solution of 2.0 g (8.0 mmol) of 6,7-dimethoxy-3,4-dihydro-isoquinoline-1-carboxylic acid ethyl ester was added to 2.0 g of 10% Pd—C. After 12 h at reflux, the reaction mixture was cooled, filtered through celite, and evaporated under reduced pressure to provide 2.0 g (98%) of 6,7-dimethoxy-isoquinoline-1-carboxylic acid ethyl ester. LCMS: 262 (M+1)+.
