HCID 21196988Methyl isoquinoline-1-carboxylateYield 50%

Procedure

A mixture of 1-isoquinolinecarboxylic acid (25 g.0.14 mol), 25 g of AMBERLYST®-15 (H+), and 300 ml of methanol was refluxed for 3 days. The reaction mixture was cooled, filtered, and the filtrate was concentrated in vacuo to afford 13.6 g (50%) of 1-isoquinolinecarboxylic acid methyl ester.
