Procedure

A mixture of (3R,6R)-3-[(R)-1-(1-methylindol-3-yl)ethyl]-6-(2-pyridylmethyl)piperazine-2,5-dione (0.10 g) and methyl iodide (5 ml) was stirred under reflux for 4 days. After evaporation of the excess methyl iodide, crude oily residue was washed with chloroform and ether, and dried in vacuo to give (3R,6R)-3-[(R)-1-(1-methylindol-3-yl)ethyl]-6-(1-methyl-2-pyridiniomethyl)piperazine-2,5-dione iodide as a solid (0.12 g).
