Procedure

4 g (10.5 mmol) of 1-methyl-4-[(1,2,3,4-tetrahydro-2-isoquinolyl)carbonyl]pyridinium iodide and 0.4 g of platinum oxide are introduced into 250 ml of methanol, and the mixture is subjected to hydrogenation for 12 h under a pressure of approximately 0.41 MPa. The catalyst is filtered off, the solvent evaporated off and the residue neutralized, and an oil is obtained which crystallizes and which is used without further treatment in the following stage.
