The deuterated compound was then treated with butyllithium in ether, with dimethoxyethane and 2N HCl regenerating the starting material.
2.
In warm deuterium oxide, 2, 4, 6-trimethylpyrylium salts undergo isotopic exchange of 4-methyl hydrogens faster than for the 2-and 6-methyl groups, allowing the synthesis of regioselectively deuterated compounds.
