Participants

Reaction Steps

By reaction and treatment in the same manner as in Example 73 and using (R)-3-{4-[4-(5-ethyl-3-methylpyridin-2-yl)piperazine-1-carbonyl]-3-methylphenyl}-4-hydroxymethyloxazolidin-2-one (150 mg) described in Example 222 and methyl iodide (21 μL), (R)-3-{4-[4-(5-ethyl-3-methylpyridin-2-yl)piperazine-1-carbonyl]-3-methylphenyl}-4-methoxymethyloxazolidin-2-one was obtained. The obtained compound was dissolved in a mixture of ethyl acetate and methanol, 4N hydrogen chloride/ethyl acetate was added, and the solvent was evaporated. To the obtained residue was added diisopropyl ether, and the mixture was filtered to give the title compound (140 mg).
