To a stirred solution of 6-hydroxy-7-methoxy-1-(3-ethoxy-benzyl)-1H-isoquinoline-2-carboxylic acid ethyl ester (6 g, 0.59 mmol) in pyridine (112 mL) was added acetic anhydride (56 mL). The reaction mixture was stirred at room temperature for 15 hrs. The mixture was concentrated in vacuo to afford 6-acetoxy-7-methoxy-1-(3-ethoxy-benzyl)-1H-isoquinoline-2-carboxylic acid ethyl ester. The crude product was used without further purification.
