実験手順

The starting material is prepared as follows: A mixture of 15 g of 4-(α-hydroxy-α-methyl-4-fluorobenzyl)- pyridine, 8.2 ml of benzyl bromide and 100 ml of acetonitrile is refluxed overnight. The solvent is evaporated and the residue recrystallized from isopropanol-diethyl ether, to yield the desired 1-benzyl-4-(α-hydroxy-α-methyl-4-fluorobenzyl)-pyridinium bromide melting at 175° with decomposition.
