Participants

Reaction Steps

To acetic acid (80 ml) are added 4-(1-chloro-6,7-dimethoxy-3-methoxycarbonylisoquinolin-4-yl)pyridine (6.11 g), sodium acetate (1.4 g) and 10% palladium-carbon (2.5 g), and the mixture is subjected to hydrogenation at 50° C. for 19 hours under pressure (2.7 atm). The palladium-carbon is removed by filtration, and the filtrate is concentrated to give 4-(6,7-dimethoxy-3-methoxycarbonylisoquinolin-4-yl)pyridine (4.84 g).
