2-(2-Bromoethoxy)tetrahydro-2H-pyran → HCID 71251922, compound

Participants

Reaction Steps

Using N-{4-[4-(2,4-dimethylphenyl)piperazine-1-carbonyl]phenyl}methanesulfonamide (271 mg) described in Example 461 and 2-(2-bromoethoxy)tetrahydropyran (1.21 mL) and by the reaction and treatment in the same manner as in Example 36, N-{4-[4-(2,4-dimethylphenyl)piperazine-1-carbonyl]phenyl}-N-[2-(tetrahydropyran-2-yloxy)ethyl]methanesulfonamide was obtained. The obtained N-{4-[4-(2,4-dimethylphenyl)piperazine-1-carbonyl]phenyl}-N-[2-(tetrahydropyran-2-yloxy)ethyl]methanesulfonamide was dissolved in methanol (5 mL), p-toluenesulfonic acid 1 hydrate (121 mg) was added, and the mixture was stirred at room temperature. To the reaction mixture was added 1N aqueous sodium hydroxide solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and the solvent was evaporated. The obtained residue was purified by column chromatography (chloroform:methanol) to give the title compound (185 mg).
